If visibility is what you're looking for, white, yellow and pink are your colors. On a cenote dive in Mexico, the diver in front of me had bright pink fins, and when we passed through a super-cloudy halocline layer when visibility dropped to just a foot or two, those pink fins were the only thing I could see!
On my last dive trip, maybe a quarter of our group had either yellow or white fins. If I hadn't started on a black/blue theme from the time I began buying gear, I might have chosen pink fins myself.
