基于Lab均匀色彩空间的色彩调和系统

对计算机辅助色彩调和工具进行研究，分析了Lab均匀色彩空间的特性，提出了可视化匀色空间的两种算法，对比其性能表现并进行了分析。根据孟赛尔色彩调和理论，构建了色彩调和的几何框架，通过调整几何框架的形状、位置、角度、匀色空间色点密度等参数，确定调和框架顶点和Lab均匀色彩空间的映射，最终获得调和的色彩设计方案。在此基础上开发了CAID软件系统中的色彩调和工具，实现了快速寻找调和色彩方案的功能。

Color Harmony System Based on Lab Perceptual Uniform Color Space

It is difficult to achieve harmonious color schemes. After studying and comparing the character of different kinds of color spaces, we found that the perceptual uniform Lab color space is helpful for this hard work. The basic idea of this method is to map the nodes of geometric framework into the color of Lab color space, so that we turn abstract harmony theory into concrete geometry design. To apply Lab color space into practical color design, methods of visualizing this color space and building the geometric frameworks in it are provided. Through adjusting the parameter of geometric framework, such as shape, position, angle and color point density of Lab color space, we can obtain different color schemes, which are harmonious. Based on this research, we developed a color design tool of computer-aided industrial design system, which enables designers get harmonious color schemes quickly.
