Problems solved by technology

[0006] The existing color systems have their own strengths, and there is no color system that can be recognized by all countries in the world so far, and the corresponding color three-dimensional model has no unified form.

Embodiment 1

[0017] A longitudinal section of embodiment 1 color sample three-dimensional standard model:

[0018] As shown in Figure 3, for a surface with a hue of blue (B) and a grade of 2.5, the chroma ranges from 2 to 14, with 2 as the division unit; the lightness ranges from 2.50 to 9.00, with 0.5 as the division unit. From a visual point of view, the lightness index and chroma index scales are perceptually uniform, and each unit represents equal perceptual differences. For color samples with the same chroma, the larger the chroma value, the more saturated, that is, the purer the color; for the color samples with the same chroma, the larger the chroma value, the brighter it is.

Embodiment 2

[0019] Embodiment 2 A cross-section of the color sample three-dimensional standard model:

[0020] For all color samples with a lightness of 6.0, divide the circle into 20 equal parts according to the hue, and the colors of the same hue are arranged according to the chroma, occupying one direction. Color samples with the same chroma are on the same circle, and the color samples on the circle with smaller radius have lower chroma. Color samples with the same lightness and different hues have different maximum saturation values, so the number of color samples on circles with different radii is also different. Visually, the shades of this section are the same.

Abstract

The invention provides a color sample solid model of color system, comprising chassis, support rod and several demonstration pieces, where the support rod is erectly fixed on the chassis, the demonstration pieces are fixed on the support rod and located on the same plane with the support rod; two surfaces of each demonstration piece are separately pasted with color pieces expressing some tones, which are arranged by the rule of using brightness as vertical axis of plane reference frame and chroma as horizontal axis of plane reference frame; the support rod can rotate round its own central axis, and the demonstration pieces are uniformly distributed around the support rod. And it is constructed based on the theory on three elements of color in Chinese color system and is a solid model corresponding to Chinese color system. And it can demonstrate change of brightness and chroma of some tone and that of tone and chroma of some brightness, able to visually help people to understand structure of Chinese color system.

Description

technical field [0001] The invention relates to a three-dimensional model of a color sample expressing a color system. Background technique [0002] The color system is a color expression model that arranges colors according to certain rules and quantitatively describes them according to human visual characteristics. The three-dimensional model is an expression of the color system. At present, the color systems widely used in the world include the Munsell color system (Munsell), the Swedish natural color system (NCS), the Ostwald color system (Ostwald) and the Japanese P.C.C.S. system. In order to express these color systems intuitively, people made corresponding three-dimensional models. However, due to the defects of the color system itself, these models also show their own defects. [0003] The Munsell color system (Munsell color system) uses a three-dimensional space model similar to a sphere to express the three basic characteristics of various colors, namely hue, li...
