When fish look up, the backdrop they most often see is the sky, so wear whites, light blues, and grays. Next, and equally important, limit overall body and boat movements. Try not to transmit noise through the boat by stomping on deck, slamming compartments, or creating little tympanic commotions by rustling through ice to find a soda. When I'm moving in on a bedded bass I pretend I'm in a deer stand up wind from a trophy buck at all times. Much like taking a shot with a bow, angle is crucial, too. The more glare between you and the bass's eyes, the more bites you're likely to score. Quality polarized glasses and keeping your distance from the fish make glare good for you, bad for the bass.
