    Air is light blue because it filters out red, which is why chlorophyl has optimized for the mix of the remaining wavelengths yellow and blue, which is green. Color theory of additive blending.

    (Our sun is slightly yellow, which is why the sky isn’t cyan and why alot of tropical plants are darker green close to brown/red)

      Are you saying that chlorophyll naturally evolved to take in specific wavelengths of light given the availability of light in specific frequencies in response to how the sun’s light moves through our amosphere? I would get it, but that would be so frustrating of a response to, “why air blue matter”.

      I mean, yeah. I’m reaching for the, “why”, though. Specifically for chlorophyll, which reflects light with a specificity. As does carotene in dying trees in the fall.
