The physicist Mach, as early as in 1922, once pointed out that several physics phenomena such as color, sound, temperature, pressure, space, time and so on, can be unified mutually by styles of every variety, in between human's mood, the emotion and the will. Color and music are extremely similar in both aspects of imagery and attribute. For instance, people sometimes can produce corresponding visual impression when their senses of hearing are stimulated. Therefore, this research would focus on the conjunction of imageries between music and color. Through the process of data mining, the correlation analysis may tell us that music image and the color image have a close relevance; moreover, music image also has the correlation with three main components of color. Transforms music image to the color image through a specific formula, afterwards transforms the color image to three main components of color. Finally, we can build a music-color transforming system based on the forgoing result. Through the experiment, most people feel the sound is accord with the corresponding color.
