There are a few cases where we know the body color of a long gone organism, such as this one. But in most cases pigments are only left in very tiny amounts, that cannot be recovered or require better technologies to do so.

In cases of the species of the Gang, at the present we have no idea what color they were. The colors of the Gang only have basis in their designer's imagination.

As Jansenov said I think the pigments of only certain species are known and I think only certain pigments/colors.  Though I've not read up on this in a while so my knowledge may be outdated.
