"The artistic pallet of tree colors is diverse. Carotenoids are like bright oil paints. The always variable
anthocyanins are like watercolors, blending across a tree covered landscape. Behind all these colors remain the
deep browns of tannins (the color of tea) and the basic light browns of tree tissues. The number of different
color combinations is almost infinite. See Appendix 1 for color expressed by species. In some forests, all the
colors contrast with evergreen trees. The colors in deciduous leaves eventually fade to brown, the color of the
earth. "
