No, with eval_pigment, one may compare the colors of two close-by points in
fractal space.  If they are identical, then there's a good chance you're out in
a field of blanket color.  I had a pretty good run of looking at fields where
the colors were dissimilar. Not all worthy of uploading to zazzle, but
certainly interesting.    I think the most interesting test (but biggest
longshot as far as remote odds) would be to look for a black spot and a
non-black spot in the same field.
