Jaime Headden has some good comments on FB about this paper, which hopefully 
will be repeated here.

But this is the same technique as used in finding the colors (or at least the 
'paint pot' aspect of color) in Sinosauropteryx,
Anchiornis, Microraptor, etc. Unless you have carbonized or mineralized skin or 
feathers, it won't work. Just skin impressions won't
do it.
