Abstract:	In this paper we present a new color measurement technique in which an innovation of a seven color ball sensor to detect the chromaticity of the tested sample was introduced. Developed with the advanced micro-processor, color ratio comparison technique, technique of the optoelectronic detection and multiplexer circuit and software design, this measurement device is capable to perform an accurately stable, high speed and multi color detection by real time measurement. By this arrangement, the seven color balls produce 5040 combinations of color. Compared with traditional spectro-photometer, the color detection error of the system is less than 0.1%. And it can be applied to classify the LED’s color luminance and chromaticity.
