I wonder in the studies of 'Do fish see color' ..if there have been studies to show if they only see value .i.e the b/w -ness of a color or actual color ?

If one takes a black and white photograph of colors in various tints/shades, you will only see them in black white. If a fish is presented with a color match to the hatch fly and it takes it, and you present another fly of equal value but different color to the fish might it also be taken for an identical fly to the earlier one?"
Just color wheels turning
