One of the main reasons that wetsuits are used is to stay warm. Black is the best color to achieve that goal. Any other color takes away some level of warmth and to me makes a suit less practical. Not only that but light colors get dirty
dirty? wow. wintertime is serious business. with strong offshores lately i'm thinking roy stuart orange colored wetsuits are the deal. maybe with marine grade reflective tape. and a rescue strobe strapped to my calf. sometimes bright colors have a function and black makes you bait.
