A novel measurement setup for determining the change in color perception due to laser protection filters is described. The developed system overcomes color space limitations common to thin-film transistor displays by using a LED illumination system, creating a large gamut covering a wide range of human color perception, and allowing adjustment of the respective spectra. An objective color matching method is used that is based on the work of MacAdam [J. Opt. Soc. Am. A 32, 247 (1942)] and enhanced by employing discrimination ellipses fitted on color discrimination thresholds on axes in the CIE 1976 USC chromaticity diagram. We present several measured color discrimination ellipses with and without laser protection filters.
