The colors are from real trees - i don't think it's too saturated
(although a lot of trees are more grayish of course) but bark has some
pretty complicated reflectivity properties and the geometry mostly is
quite tricky as well (often there is a layered structure leading to pretty
flat and shiny 'plateaus' between rougher parts).
