| Aug 28, 2021 at 16:47 | comment | added | AlexP | @jamesqf: Blue at macro scale is not necessarily different from blue at molecular scales, except in so much that all colors are different at molecular scales. There are quite a few animals and very many plants which make honest-to-goodness blue pigments; and there are situations where colors other than blue are obtained by structural interference. And, of course, not all photosynthetic pigments are green. | |

| Aug 27, 2021 at 12:34 | comment | added | DWKraus | I have to agree with AlexP. Kind of definitionally, it's a pigment if it absorbs light in the way you are describing. If it scatters light instead, it's not absorbing it and retaining the energy. | |
| Aug 27, 2021 at 6:17 | comment | added | AlexP | "Microscopic structures that trap light": I am not sure that I understand what is it that you think photosynthetic pigments are, if not microscopic structures that trap light. | |
