In this study, the theoretical investigations into the color preferences of "gender" are explored and validated. The combination of in-kind statistic and color preference theories are first discussed in this paper. The basins, cell phones, and color tickets are used for the questionnaire.It is found that the "gender" is the easier variable to show the differences of color preferences. There are the results in this paper: 1. Males like vivid tone and females prefer the light tone color. 2. In monochrome, males like blue system but dislike olive and red purple; females prefer red system but dislike olive and dark greenish blue. 3. The "gender" is really an important factor because there are 18 colors (more than one-third of the total samples) and 8 nauseous colors shown in significant differences of personal color preferences. 4. In basins, the preferred colors are sky blue and white; the disliked colors are grayish yellowish orange, black and vivid purplish blue. And the significant different colors in basins are pink reddish orange, soft reddish orange, vivid yellowish green, and soft yellow green. However, in cell phones, the significant different colors are vivid purplish red, dark red purple, pink purplish red, dark olive, deep violet, brown orange, white, light grayish violet, and black. The preferred colors in cell phones are white, black and vivid purplish red; the disliked colors are brown orange, bright yellow and dark olive.
