I would go with a dull or dark color pattern for females and a brighter color pattern for males. The reasoning for this is that in nature many animals have this kind of color pattern to attract mates. The brighter the colors on the male the more likely he is to get a mate. Though one dose need to take into account for species, behavior, and enviorment. Sorry almost lost sight of the topic at hand. Tiger shark patterns in a green color.
