Is compton scattering the reason why different substance have different colors? I was thinking along the lines of substanes with higher energy electrons around the atom wouldn't cause too much of a change in the photons wavelength and atoms with lower energy electrons will absorb more energy and would cause a more dramatic increase in wavelength. I have thought of flaws in my thinking like why when shine a blue light on something the light doesn't comes back to my eyes green, which I have never known to happen. But I was really just wanting to know if Compton scattering contributes to color in any way? Most definitions only seem to talk of gamma quanta and x-rays, so maybe the effect only happens with such high energy photons so we could never see it with our own eyes, but I'm just curious.
