As far I know, that is just something strange that doesn't get them any energie. Some extra pigment that made it look red, but further completely useless.

Numsgil:
Actually I think it's a lack of pigment.  Without chlorophyl leaves look red.

bacillus:
Meaning red light is not absorbed...
Leaves without any form of chlorophyll whatsoever actually look white, which is how variegated leaves form. There are plants with purely red leaves, so what you're saying is that they can't produce sugars in significant quantities.

Peter:
If leaves drop from the trees many leaves become red, this is becouse chlorophyl dies and the red stays left. I think there are plenty leaves that have some red pigment, but normally not shown. And so I think red leaves just have more of that red pigment. Possible a little less chlorophyl but I doubt that would be much.

We're getting more and more biological here aren't we.

bacillus:
I'm afraid so
