>I don't know about being color blind, but several of the sources I found while playing with this one mentioned that insects have eyes that are sensitive to the wavelengths that are reflected by this and are attracted to it. Whether that represents "color" vision or not I don't have a clue. I can post the text of one of the sources tomorrow if you like. It is an interesting topic. There are some other advantages to the tree making it from what I read. It also tends to protect the DNA in the leaves from the harmful effects of UV radiation from the direct sunlight. Plants are interesting in their adaptations.
