Abstract

Difference of tristimulus values of different colors under light source of sunlight and D65 was compared in the 380nm to 800nm wavelength range. The color difference of same samples in the two light sources was analyzed using CIE1976L*a*b* color space. The results showed that standard light source of sunlight for investigation and detection of optical camouflage is more objective and accurate.
