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.
