Under water, past around 2 feet, reds change to various shades of grey and black for most fish. They still like the "color" if it represents food to them, but there are studies showing that many colors turn to other shades in the fishy world.
i think they have a different colour spectrum to us, but definately see some colour for sure. though yea if its black and white, or more than one colour(preferably different shades and not similar (like red and orange) i would imagine it to be easier to detect it moving and i guess would look more alive
Fish definitely see color, maybe not the way we see it, but they can definitely tell the difference. Fish actually see colors we can't see, such as ultra violet. A scientist invented an attractant based on this ultra violet detection, it's called fool-a-fish. It uses titanium dioxide, which refracts UV, which fish can see much farther away than other colors, supposedly. I want to give it a try this summer.
