Then I don't understand why you still want to analyze colors instead
of analyzing faces.  This is what my suggestion boiled down to:
instead of trying to figure out the foreground color of the text at
point, just compare its face(s) with a list of known faces whose
appearance you don't want to override.

Of course, I did.  But it still talks about colors, something I
suggested to avoid.
