I tried all kinds of suits, black, camo, short, long i must say i did not feel a lot of difference. I am guessing it would make more difference in areas where visibility is not very good, such as in areas in the med or around some kelp beds, maybe then wetsuits mimicing the surroundings would make some difference. Over here visibility is very good and most of the hunting is not ambush style so thats why i have this opinion.
Again, i would conclude by saying, it depends on the area you fish in and the type of fish (accordingly hunting style).

cheers
