Might want to add a "don't view my post in ubbthreads-dark" line to your sig. [some readers could get awfully confused otherwise. i.e., the "s" is all but invisible.]
FWIW, my 3 'colors-of-choice' which seem to work well in both light and dark themes are: FF6600, 33CC00, and 3366FF (all on row 4 of the palette).
i.e., the "s" is all but invisible.]
