Harmonious Color Identification in Uniform Color Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing color spaces, such as CIELAB, are device-independent but not perceptually uniform, making it difficult to automatically identify harmonious colors across different devices and platforms.
Innovation Solution
Utilizing a uniform color space like OSA-UCS, and employing a cleavage surface based on harmonious color sets to automatically identify harmonious colors, leveraging data from social media, product catalogs, and surveys to determine subjective effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CIELAB color space is used for device-independent color representation, then color consistency across devices is improved, but perceptual uniformity deteriorates making automatic harmony identification difficult
Solution Approach 1:
The patent transforms color data from CIELAB space to OSA-UCS color space, changing the parameter representation from (L*, a*, b*) to (R, Y, B). This parameter transformation enables perceptual uniformity while maintaining device-independent color consistency, allowing automatic identification of harmonious colors through geometric relationships in the transformed space.
2Ease of operation
If traditional color wheel methods are used for color harmony identification, then ease of operation is improved, but adaptability to different devices and platforms deteriorates
Solution Approach 1:
The patent creates a universal color harmony identification system that works across different devices and platforms by using the OSA-UCS color space. The cleavage surface methodology provides a device-independent framework that maintains ease of automatic color selection while achieving cross-device compatibility through perceptually uniform color representation.
Data Source
AI summary
In some embodiments, a computer-implemented method of automatically determining harmonious colors is provided. A computing system receives a selection of a color, and uses the selected color to retrieve a cleavage surface in a uniform color space. The computing system presents one or more other colors from the cleavage surface as harmonious colors with respect to the selected color.
