Hmm, don't you mean "former"?  It is the warm-blooded issue for
which the evidence is equivocal.  In fact there is good reason
to conclude that dinosaurs had a physiology that doesn't fit
well in the modern classification (neither warm-blooded nor cold).

For color, the widespread occurance of display structures:
hadrosaur crests, ceratopsian frills (shields), theropod
ridges and crests, and so on indicate a very visual type of
animal.  Then you add the fact that their descendents, the
birds, are very colorful, and the sum total is fairly convincing.
[Note, except for Triceratops, the neck frill bones of ceratopsians
have big holes in them, making then useless as shields, which
leaves only display].
