Abstract: A color measurement system includes a multi-purpose filter and optics assembly. The filter and optics assembly includes at least one tube array for segmenting received light. The segmented light is mixed and the polarization qualities of the light are modified so to minimize the effects caused by angular adjustments. A diffuser mixes the segmented light. Additionally, the color measurement system includes an ambient light attachment for collecting light from the viewing area surrounding the computer display. The ambient light collected is then analyzed, and a viewing area profile is created. The viewing area profile then can be used by software to adjust the colors displayed on the computer displays.
