basicly nobody has cracked the whole story yet or we would all use the same lure. when it comes to color difrent fish see them diferently and all are difrent to us. so an exact match on the deck of a boat is meaningless. coulors change at various depts for example you cant see red at depth without artifical light. ultraviolate is a pritty important coulor with lures but is rarly used becase the fisherman cant see it. visability changes color. refletion changes aparent color transparincy is a bit important. but even that is insignificant becase fish will only chase what it can catch as in its dying or slow ect, or anoyes them enough and provokes a responce. noise is a important to get right too
