If I use the drop-down menu in Cacti’s UI to select colors, FireFox can show the colors on the menu:
Neither Safari, DeerPark (the CPU-optimized FireFox variant), or Camino can do it.
I won’t ask how hard it is — I’m sure it’s beyond my limited grasp — but perhaps the FireFox crew won’t mind sharing?

I believe the problem there is that in the regular Firefox, the dropdown box is actually drawn by Firefox itself, but in Safari, Deer Park, and Camino, the dropdown is sent to the OS to be drawn, and it either doesn’t know how to handle option colours or Firefox doesn’t tell the OS what colours to draw things in.
I am neither a lawyer nor a Firefox engineer, but this is a Best Guess™. Hope it helps :)
