Description

Technical Field

[0001] The present invention relates to the field of color mixing, and particularly to a method and tool for mixing pigments. Background Art

[0002] In many fields such as painting, design, and industry, color matching has always been a core skill. In related technologies, most color mixing methods rely on the mixer to manually mix colors close to the target color by relying on intuitive visual perception and long-term accumulated experience.

[0003] However, this method overly relies on the individual's sensory acuity and experience, is greatly interfered by environmental factors, and lacks scientific and systematic color mixing means, thus having defects in the efficiency and accuracy of color mixing. Summary of the Invention

[0004] The purpose of the present invention is to provide a method and tool for mixing pigments, so as to solve the problem of insufficient efficiency and accuracy of color mixing in the prior art.

[0005] To solve the above technical problems, the present invention provides a method for mixing pigments, including: obtaining a first lightness value of a target color; based on black pigment and white pigment, mixing a first formulated pigment according to a preset ratio corresponding to the first lightness value; wherein, the lightness of the first formulated pigment is the first lightness value; based on a basic hue pigment, mixing a second formulated pigment; wherein, the lightness of the second formulated pigment is the first lightness value, and the hue of the second formulated pigment is the hue of the target color; mixing the first formulated pigment and the second formulated pigment to obtain a final formulated pigment.

[0006] The present invention also provides a tool for mixing pigments for implementing the above-mentioned method for mixing pigments, including: a lightness calibration scale, on which there are reference holes for indicating different lightness values; a hue calibration scale, on which there are reference holes for indicating different gray levels.

[0007] In the embodiments of the present invention, since both the first formulated pigment and the second formulated pigment maintain the same lightness as the target color, the lightness of the final pigment after mixing will not change due to the change of the mixing ratio, fundamentally solving the problem of lightness deviation caused by subjective mixing in the traditional color mixing process. And, on the premise that the lightness is guaranteed, the mixer can fine-tune only the cold-warm and saturation of the hue by adjusting the mixing ratio of the two formulated pigments, making the color matching more accurate and stable. In addition, the embodiments of the present invention rely on lightness calibration and preset mixing ratios to overcome the uncertainty of relying on the intuitive experience of the mixer in the traditional color mixing method, making the color mixing process have high repeatability and controllability, and being applicable to a variety of actual color mixing scenarios.

[0015] In many fields such as painting, design, and industry, color mixing has always been regarded as a core skill, and its accuracy is directly related to visual effects, product quality, and artistic expressiveness. However, the color mixing methods commonly used in the prior art mainly rely on the mixer to gradually mix colors close to the target color through manual operation based on intuitive visual perception and long-term accumulated experience. This method has the following obvious deficiencies:

[0016] 1. High subjectivity and individual differences: The mixer must undergo long-term training to obtain a relatively satisfactory color mixing result in intuitive judgment. However, there are huge differences in the visual sensitivity and experience accumulation of different people, resulting in significant differences in the effects of the same color mixed by different operators. Moreover, the sensitivity of the human eye to colors is not only affected by congenital factors but also fluctuates due to fatigue, mood, or environmental changes, making the color mixing result lack stability and repeatability.

[0017] 2. Interference from environmental factors: During the actual color matching process, factors such as ambient light and background color can cause visual errors. For example, the Bezold effect can make the target color appear brighter or darker against different backgrounds, directly affecting the judgment of the color matcher. Moreover, since the brain's color constancy depends on environmental reference, it is difficult to overcome the interference caused by changes in the external environment solely relying on intuitive feelings, resulting in inaccurate color matching during color adjustment.

[0018] 3. Lack of scientific and systematic color adjustment methods: Traditional color adjustment methods lack quantitative indicators and standardized tools. The color adjustment process is mostly "trial and error", lacking scientific control over parameters such as color brightness, saturation, and hue, resulting in the lack of clear logic and data support for color adjustment.

[0019] 4. Low efficiency and poor repeatability: Due to the lack of scientific basis, color matchers often need to try repeatedly, approaching the target color by continuously adjusting the proportion of pigments. This not only takes time and effort but also easily leads to unstable final color adjustment results due to the accumulation of errors in each operation. Moreover, in industrial production or real-time design applications, the color adjustment efficiency directly affects the production rhythm and creative process, and traditional methods are difficult to meet the requirements of fast and accurate color adjustment when used intensively.

[0020] In summary, the existing color adjustment methods overly rely on the intuitive feelings and personal experience of color matchers, unable to provide a scientific and standardized color adjustment process. They are not only easily interfered by environmental factors but also difficult to ensure the consistency and high precision of color matching. These deficiencies not only limit the free play of artistic creation but also restrict the improvement of product quality and production efficiency in industries and design fields. Therefore, there is an urgent need to develop a new color adjustment method based on objective data and systematic processes to achieve precise control of various color parameters (such as lightness, hue, saturation, etc.), thereby significantly improving the efficiency and accuracy of color adjustment.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in the embodiments of the present invention, many technical details are provided to help readers better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed by the present invention can still be implemented. The following division of each embodiment is for convenience of description and should not constitute any limitation to the specific implementation manner of the present invention. Each embodiment can be combined and cross-referenced with each other on the premise of no contradiction.

[0022] One embodiment of the present invention relates to a method for color mixing of pigments, which can be applied to color mixing tools or palettes, or can also be embedded in dedicated color mixing instruments, industrial control systems or server sides, and realizes the acquisition, processing, matching and output of color data through corresponding software and hardware platforms, so as to meet the requirements of various application scenarios such as artistic creation, industrial production and real-time color mixing. The present invention obtains the first lightness value of the target color; based on black pigment and white pigment, prepares a first formulated pigment according to a preset ratio corresponding to the first lightness value; wherein, the lightness of the first formulated pigment is the first lightness value; based on the basic hue pigment, prepares a second formulated pigment; wherein, the lightness of the second formulated pigment is the first lightness value, and the hue of the second formulated pigment is the hue of the target color; mixes the first formulated pigment and the second formulated pigment to obtain the final formulated pigment. In the embodiment of the present invention, since both the first formulated pigment and the second formulated pigment maintain the same lightness as the target color, the lightness of the final pigment after mixing will not change due to the change of the mixing ratio, fundamentally solving the problem of lightness deviation caused by subjective mixing in the traditional color mixing process. And, on the premise that the lightness is guaranteed, the color mixer can fine-tune only the coldness / warmth and saturation of the hue by adjusting the mixing ratio of the two formulated pigments, making the color matching more accurate and stable. In addition, the embodiment of the present invention relies on lightness calibration and preset mixing ratio, overcomes the uncertainty of the traditional color mixing method relying on the intuitive experience of the color mixer, makes the color mixing process have high repeatability and controllability, and is applicable to a variety of actual color mixing scenarios.

[0023] The implementation details of a method for color mixing of pigments in the embodiments of the present invention are specifically described below. The following content is only provided for convenient understanding of the implementation details and is not necessary for implementing this solution.

[0024] The present invention executes steps as Figure 1 shown, including steps 101 to 104, specifically as follows:

[0025] In step 101, obtain the first lightness value of the target color.

[0026] Specifically, in the above step 101, obtain the first lightness value (i.e., gray value) of the target color through a lightness calibration scale. Specifically, it includes: using the color sampling unit on the lightness calibration scale to compare with the target color; wherein, at least two color sampling units are set on the lightness calibration scale, and each color sampling unit includes a color sampling hole and a lightness value scale, and the color sampling hole is used to compare the lightness value of the target color; select the lightness value scale of the color sampling unit that matches the lightness value of the target color as the first lightness value.

[0027] It should be noted that when measuring the lightness value using the above lightness calibration ruler, the lightness calibration ruler is continuously adjusted so that each color sampling hole can be directly compared with the target color until it is found that the gray-scale color of a certain color sampling hole is the same as the lightness of the target color, which is considered a successful match. At this time, the lightness value scale corresponding to the current color sampling hole is read as the lightness value of the target color for subsequent pigment mixing.

[0028] Optionally, in one embodiment, the above lightness calibration ruler arranges the color sampling units in the progressive order of the lightness value scale, making it easier for the color mixer to judge the lightness of the target color. For example, the progressive order of the lightness value scale can be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

[0029] Optionally, as Figure 2 , the lightness calibration ruler in the above embodiment is designed as a rectangular ruler, and its color sampling units are arranged in a progressive order along the same direction. Each color sampling unit sequentially includes a lightness value scale, a matte coated paper, and a color sampling hole from left to right. Among them, the lightness value scale is used to display standard lightness values (for example, from 0 to 10). The matte coated paper is matte processed to ensure stable reflection under different ambient light conditions. This part shows preset gray-scale colors, and the matte coated papers of different color sampling units have different lightness displays. The color sampling hole is used to align with the target color for comparison.

[0030] Optionally, the above lightness calibration ruler can be made of a flexible material for rolling up storage or folding for carrying. This form can also display a continuous progressive gray scale in a long strip shape and is suitable for on-site measurement of irregular or large-area target colors, thus being suitable for outdoor or on-site working environments.

[0031] Optionally, as another alternative, the lightness calibration ruler can also be designed in the form of a roulette, that is, multiple color sampling units are arranged in a fan shape to form a circular or semi-circular structure. Among them, the color sampling units are distributed in the form of fan-shaped slices, and each fan-shaped area also includes a lightness value scale, a matte coated paper, and a color sampling hole. Different fan-shaped areas represent different lightness values, usually distributed in ascending order to form a continuous lightness gradient. When in use, the user rotates the roulette so that a certain color sampling unit is in the observation position and aligned with the target color. Similar to the rectangular calibration ruler, when the gray-scale color displayed by the matte coated paper of a certain fan-shaped color sampling unit on the roulette matches the target color, the lightness value corresponding to this unit can be read.

[0032] It should be noted that the above target colors include the colors of physical objects or the colors presented on the display screen of an electronic device. That is, the target objects of the colors that can be formulated in the present invention can be the colors of physical objects such as tables, platforms, buildings, etc., or the colors presented on the display screens of electronic devices such as mobile phone screens, computer screens, televisions, electronic photo albums, etc.

[0033] In the above method, the lightness calibration scale obtains the corresponding lightness value through the reflectance of the following target colors, and the specific mapping relationship is shown in Table 1 below:

[0034] Table 1

[0035] Brightness value 0 1 2 3 4 5 6 7 8 9 10 RLV Reflectance (%) 0 5 10 20 30 50 70 80 90 95 100

[0036] Optionally, in one embodiment, to avoid errors caused by changes in ambient light, after multiple comparisons, the average value can be taken or the most frequently occurring matching value can be used to ensure the stability of lightness measurement.

[0037] In step 102, based on black pigment and white pigment, a first formulated pigment is prepared according to a preset ratio corresponding to the first lightness value (i.e., the target gray-scale pigment ratio); wherein, the lightness of the first formulated pigment is the first lightness value.

[0038] Optionally, the above preparation method can be as follows: first, calculate the masses of black pigment and white pigment required according to the mass of the first formulated pigment to be prepared and the target gray-scale pigment ratio, then prepare the corresponding masses of black pigment and white pigment according to the calculation results, and finally uniformly mix the two pigments to obtain the first formulated pigment.

[0039] Optionally, the above preparation method can also be as follows: first, take black pigment with a mass of a, and then successively add white pigment with a mass of a to the black pigment until the mixing ratio of black pigment and white pigment is equal to the target gray-scale pigment ratio.

[0040] Specifically, in step 102, the goal is to prepare a pure gray-scale (achromatic) formulated pigment whose lightness is consistent with the first lightness value obtained by the lightness calibration scale in step 101. For this purpose, a set of mixing ratios of black pigment and white pigment are preset, and these ratios are correspondingly adjusted based on different values of the lightness scale, so as to achieve the goal of formulating the target lightness. As Figure 3 shown, through this preset ratio, when the lightness of the target color is determined (i.e., Figure 3 after the lightness calibration scale is used), the ratio of black pigment and white pigment can be directly obtained by looking up the table according to the corresponding ratio, and according to Figure 3 the "Rmix separation method steps", black and black pigments are mixed in proportion to obtain the first formulated pigment (i.e., pure gray-scale pigment) with the same lightness as the target lightness.

[0041] Specifically, as Figure 4 shown, the mixing ratios of black pigment and white pigment with different lightness values are as follows:

[0042] When the lightness value scale of the color sampling unit is 0, the ratio of the black pigment to the white pigment in the preset ratio is 1:0; or,

[0043] When the lightness value scale of the color sampling unit matching the lightness value of the target color is 1, the ratio of the black pigment to the white pigment in the preset ratio is 1:1; or,

[0044] When the lightness value scale of the color sampling unit matching the lightness value of the target color is 2, the ratio of the black pigment to the white pigment in the preset ratio is 1:2; or,

[0045] When the lightness value scale of the color sampling unit matching the lightness value of the target color is 3, the ratio of the black pigment to the white pigment in the preset ratio is 1:3; or,

[0046] When the lightness value scale of the color sampling unit matching the lightness value of the target color is 4, the ratio of the black pigment to the white pigment in the preset ratio is 1:4; or,

[0047] When the lightness value scale of the color sampling unit matching the lightness value of the target color is 5, the ratio of the black pigment to the white pigment in the preset ratio is 1:5; or,

[0048] When the lightness value scale of the color sampling unit matching the lightness value of the target color is 6, the ratio of the black pigment to the white pigment in the preset ratio is 1:6; or,

[0049] When the lightness value scale of the color sampling unit matching the lightness value of the target color is 7, the ratio of the black pigment to the white pigment in the preset ratio is 1:7; or,

[0050] When the lightness value scale of the color sampling unit matching the lightness value of the target color is 8, the ratio of the black pigment to the white pigment in the preset ratio is 1:8; or,

[0051] When the lightness value scale of the color sampling unit matching the lightness value of the target color is 9, the ratio of the black pigment to the white pigment in the preset ratio is 1:9; or,

[0052] When the brightness value scale of the color sampling unit matching the brightness value of the target color is 10, the ratio of the black pigment to the white pigment in the preset ratio is 0:1.

[0053] It should be noted that in actual operation, since the range and interval of the scales on the brightness calibration scale may not be strictly linear, the ratio of the black pigment to the white pigment needs to be adjusted according to a pre-determined specific relationship. For example, if the change between the scales is non-linear (such as logarithmic or power function relationship), the ratio also needs to be adjusted according to the corresponding non-linear mathematical formula, rather than simply the 1:scale value ratio.

[0054] In the above step 102, compared with the traditional method of directly mixing the target color, this solution has more advantages by separating the brightness (luminance) for ratio matching and then mixing the gray-scale pigment in combination with the preset ratio. Based on the sensitivity of the rod cells in the human retina to light and dark, this solution identifies the brightness value of the target color through the brightness calibration scale, and then mixes the black and white pigments according to the preset ratio to ensure that the gray-scale pigment prepared is exactly the same as the brightness of the target color. This method overcomes the errors caused by subjective perception in the direct color mixing process, thus greatly improving the scientificity and accuracy of the mixing result.

[0055] In step 103, based on the basic hue pigment, a second formulated pigment is prepared; wherein, the brightness of the second formulated pigment is the first brightness value, and the hue of the second formulated pigment is the hue of the target color.

[0056] Specifically, the above step 103 specifically includes: obtaining the hue of the target color through the hue calibration scale; preparing an intermediate formulated pigment with the hue of the target color based on the basic hue pigment; adding white pigment to the intermediate formulated pigment until the brightness value of the intermediate formulated pigment reaches the first brightness value to obtain the second formulated pigment.

[0057] Specifically, in the above embodiment, the above hue calibration scale is composed of multiple hue sampling units, and each unit represents a standard hue, such as red, orange, yellow, green, blue, purple, etc. The operation of the hue calibration scale is similar to that of the brightness calibration scale. The hue calibration scale is compared with the target color to determine the hue of the sampling unit matching the target color.

[0058] Then, based on the target hue, an intermediate formulated pigment with a preliminary hue of the target color is prepared by selecting or mixing the basic hue pigments. In this process, different basic hue pigments can be mixed according to a predetermined ratio, or mixed according to the experience and visual inspection of the mixer. At this stage, the main focus is on the hue and saturation, and the target tone is initially achieved, but the brightness may not be exactly the same as the target color.

[0059] Finally, after formulating the intermediate formula pigment with the hue of the target color, its lightness is increased by gradually adding white pigment. When adding white pigment, it needs to be done step by step. After each addition, the lightness of the mixture is detected to ensure that the color gradually approaches the predetermined first lightness value while maintaining the target hue. When the lightness of the intermediate formula pigment reaches the same as the first lightness value after adding white pigment, the resulting mixture is the second formula pigment.

[0060] In step 103, this solution formulates the hue and lightness in stages respectively. First, in the hue formulation stage, according to the sensitivity of cone cells in the human retina to colors, the intermediate formula pigment consistent with the target color is formulated using the basic hue pigment. This stage focuses on replicating the hue of the target color and does not strictly match the lightness for the time being. Subsequently, in the lightness adjustment stage, aiming at the possible lightness deviation in the preliminary formulation, taking advantage of the sensitivity of rod cells in the human retina to brightness, white pigment is gradually added to increase the lightness of the mixture until it reaches the first lightness value measured by the lightness calibration scale in step 101, so as to achieve the accurate restoration of the final color without changing the hue.

[0061] In step 104, the first formula pigment and the second formula pigment are mixed to obtain the final formula pigment.

[0062] Specifically, in the above step 104, the mixing ratio of the first formula pigment and the second formula pigment can be continuously adjusted until the saturation of the mixing result matches the saturation of the target color, and the final formula pigment is obtained.

[0063] The above target color mixing method is based on Figure 5 the Rmix separation method shown in

[0064] Cmix = R1×P1 + R2×P2, and R1 = R2;

[0065] wherein, R1 and R2 respectively represent the lightness values containing only the gray component and only the hue component; P1 and P2 respectively represent the mixing ratios of these two parts (satisfying P1 + P2 = 1P1 + P2 = 1P1 + P2 = 1). Since the values of R1 and R2 are the same, this formula ensures that the overall lightness of the final mixed color always remains R regardless of how the mixing ratio changes; at the same time, only by changing the ratio of P1 to P2 can the saturation and hue of the color be adjusted.

[0066] In the implementation of step 104, the formulating personnel continuously adjust the mixing ratio of the first formulated pigment providing the gray component and the second formulated pigment providing the target hue according to the above Cmix formula until the saturation and hue of the mixing result are exactly matched with the target color. Specifically, when P1 increases, the color produced tends to be gray; while when P2 increases, the color produced is closer to the target hue. This not only ensures the constancy of the color lightness but also realizes the fine control of saturation and hue, thus constructing a scientific and standardized color mixing scheme.

[0067] It should be noted that the target color in the color mixing method implemented in the above steps 101 to 104 can be one, or two or more. When the target color is two or more, a color palette can be used to mix multiple target colors. The method includes: for each of the at least two target colors, arranging the first formulated pigment obtained during the formulating process along the first direction of the color palette, and at the same time arranging the second formulated pigment along the second direction intersecting the first direction.

[0068] Optionally, when separating colors for multiple target colors simultaneously, it can be carried out through the steps as Figure 6 shown. First, use the lightness calibration ruler as Figure 6 shown to compare with different parts (highlight / dark part) of each target object, select 5 gray scale ratios (such as lightness scales 1, 2, 4, 7, 9, etc.), and based on the preset ratio, construct pigments with only lightness and place them on the number axis in sequence along the vertical number axis (Y-axis). Then, for each target color, compare it with a hue calibration ruler or basic hue pigments respectively to obtain the corresponding hue information. Formulate the pigments of each hue in sequence and arrange the hue pigments horizontally (X-axis); then through the way of grid intersection (see the color palette example in Figure 6 ), the corresponding "lightness + hue" combinations can be formulated at each intersection point, and then multiple pigments with corresponding target colors can be obtained.

[0069] In the above embodiments, multiple target colors can be formulated in sequence, that is, after formulating the final formulated pigment of one target color, then proceed to formulate the final pigment formula of the next target color. It is also possible to first formulate all the first formulated pigments of multiple target colors, then formulate all the second formulated pigments of multiple target colors, and finally, based on the first formulated pigment and the second formulated pigment of each target color in sequence, formulate each final color formula.

[0070] In the embodiments of the present invention, since both the first formulated pigment and the second formulated pigment maintain the same lightness as the target color, the lightness of the final pigment after mixing will not change due to the change of the mixing ratio, fundamentally solving the problem of lightness deviation caused by subjective mixing in the traditional color matching process. Moreover, on the premise that the lightness is guaranteed, the color matcher can fine-tune only the cold-warm and saturation of the hue by adjusting the mixing ratio of the two formulated pigments, making the color matching more accurate and stable. In addition, relying on the lightness calibration and the preset mixing ratio, the embodiments of the present invention overcome the uncertainty of the traditional color matching method relying on the intuitive experience of the color matcher, making the color matching process have high repeatability and controllability, and being applicable to a variety of actual color matching scenarios.

[0071] Meanwhile, the design inspiration of the color matching method provided by the embodiments of the present invention relies on the human visual physiological principle, that is, the color perception principle of cone cells and rod cells in the human retina. Cone cells are mainly responsible for the perception of hue and are sensitive to light of different wavelengths, thus accurately capturing the tone of the color; while rod cells mainly perceive the intensity of light and determine the brightness and darkness. Therefore, in the present invention, the lightness and hue are independently adjusted respectively, which not only conforms to the processing mechanism of the human visual system, but also makes the color matching process more scientific and efficient.
