Abstract:
In architectural design, building color determination is one of the most important steps. Due to the numbers of color producers and color lists, to select the color which has the color value and qualifications that match the desianer's requirements is very difficult and wastes time. In the case where the designer chooses the color which is not on the color lists, he has to mix it from the existing colors. In order to avoid errors in mixing colors, experience and color theory understanding is needed. Therefore, the purpose of this study is to develop computer software for color matching and to simulate color mixing by setting color ratios on the computer. Color matching calculation by computer is used in coordinates system of color positions and the distance between each position to get the matched color. Because of it's ability in identifying color ranges, the HSL color model is used in color matching. Moreover, this model can make color matching more convenient and accurate. Color mixing simulation by setting color ratios on the computer is used to find the position between 2 points on the primary color line in the HSL color model that can explain the pigment color mixing characteristics. Furthermore, it can determine the color mixing ratio and primary color can be any color without any limitations. In conclusion, the developed software testing shows that it gives the correct and accurate color matching and mixing color pigment which can be applied to architectural design.
