What are the chances that some of the pigments might be long lived and 
available in the rock matrix around some fossils. I have no good idea if 
any pigments are longer lived than chlorophyll, xanthophyll, carotene and 
the like but someone may know. I am reminded of the kid? that found skin 
impressions in digs where the bone folks hafd ignored or missed the 
impressions. Could remnants, no necessarily visible, tell of color in 
some instances?
