Why is green light not used in photosynthesis? --

Supposedly because the first sea-based plant life used a different photochemical reaction with _did_ use green light (and was thus purple), and was supplanted by modern plants which used the remaining green light more efficiently. Cites needed, though, before this gets into the article.
Some stone fruit trees have leaves that are a dark red/purple colour. I note there is no chlorophyll variant listed that is that colour, or anything like it. Is the colour of these leaves due to a non-photosynthetic pigment? Around here there are leaves in just about every colour except blue. (Green is the most common though.)
Absolutely no source I have ever seen counts carotene and xanthophyll as components of chlorophyll, but rather as pigments that are present along with chlorophyll inside chloroplasts. Are we sure this is the approach we want to take? Also, the article is somewhat green plant biased (eg chlorophylls a and b, which are not present together in most
algae).
Yes, sorry, you are right. They are all
photosynthetic pigments not chlorphylls. I have created a new page. --
