The color variation for automobile exterior paint has been increasing according to flake pigments application. To improve analytical development of colors, multi-angle color measurement has been developed, also computer graphics has been utilized to visualize it. There is a system based on multi-angle color spectrum data to visualize automobile paint color. On this work, it is possible to propose measurement and visualization for more accurate color image by using micro-brilliance parameters. It will achieve more reliable virtual color design and development with the system. By using high gain CCD system, micro-brilliance texture can be measured more clearly. This result has been analyzed by histogram to calculate BS (ratio of Background Surface area) that is the ratio of lower brightness area than AB (Average Brightness of all). About 51 silver metallic samples, BS has been measured and visual rating of color expert and general users has been evaluated. It has been found that the visual ratings of these are good correlate. And value of BS correlate to visual rating between 'smooth' and 'glitter' these mean micro-brilliance texture. These mean it is possible to measure visual rating of not only expert but also general user, and it is important to measure micro-brilliance. To visualize micro-brilliance, a new logical procedure has been developed based on micro-brilliance parameters from histogram analysis. On this logic a layered system for each data of three parts has been used. Therefore the procedure has compatibility of average brightness. By using this micro-brilliance image on computer graphicshas been simulated based on multi-angle color spectrum data. As above, this system has compatibility of average color spectrum data. The reality of rendered image improved. This measuring and visualizing system makes virtual color design more accurate and reliable. It will be achieved stronger relationship between design and technical research and development.
