Why is the absorption spectrum more useful for defining the colors we see as opposed to emission spectrum?


@intelligentDungBeetle The point of this slide is that a spectral description of color is far more accurate than a low-dimensional color model like RGB or CMYK. The question of emission, absorption, etc., spectra is just a matter of what phenomenon you're trying to describe (are you modeling a light bulb? or reflected light? Etc.)
