I don't think it matters a whole lot mate, as OPB has said, movement is what busts you. One thing to think about though, there is actually very few solid black colours in nature.
Only complaint I have with my black bow is it shows scratches really bad, camo seems to blend the scratches in better. Shot my bull last year at 12 yards in the desert he never looked at me when I picked up my bow a drew I doubt its an issue
