You're totally right, thanks for being patient with me. It should have been obvious, but I hadn't initially made this connection:

> Only the green algae and their descendants, the land plants, do not absorb green light

The earlier sources that I found had a bias towards land plants.

I'm much happier to accept as mere coincidence the fact that land plants evolved from a specific kind of algae (i.e. one that might have adapted for absorbtion of light at a certain depth and therefore shows a preference for absorbing blues over greens) and not some other kind which would've had different preferences.

Initially I thought that each of the green pigments I listed had evolved separately on land and it seemed rather spooky that they shied away from green. But that's likely not where they evolved, so now it's not spooky.
