The human eye cannot tell the difference between such light spectra just by looking into the light source, although the color rendering index of each light source may affect the color of objects illuminated by these metameric light sources. Similarly, most human color perceptions can be generated by a mixture of three colors called primaries ...
The color of red and other pigments is determined by the way it absorbs certain parts of the spectrum of visible light and reflects the others.
