I should have been more clear that I was asking about the numbers in the
paint color's *names, *not the numbers of the paint colors themselves (RGB
triplets).
I wanted to verify if the Caret-assigned color name ("Unknown_name_#") was
related to the value defining the ROI identified by that color name. I was
mostly worried because I couldn't find documentation to verify that it was
a correct assumption, but I've checked by using a single ROI (for example,
defined by the 3's in a brain of 0's) and the assigned color name came out
to be "Unknown_name_3".
Thanks for responding, Donna!
