Change of the color characteristics of light reflected by a nonabsorbing isotropic plane-parallel slab under different illumination conditions

It is shown that for standard colorimetric light sources (illuminants) A an d C a change in the angle of incidence of the light on a transparent colorl ess glass slab will lead to slight changes in the coordinates of the chroma ticity of the reflected light, but the color differences of the incident an d reflected light can reach several tens of threshold units and increases a s the angle of incidence is increased.
