At least that is what the textbooks tell us. Hence when a person lacks a particular type of cone he s considered colorblind.
The science community has been going back and forth on whether or not octopuses are able to see color. But cephalopods a group that includes octopuses squid and cuttlefish have only 1 type of light receptor in their eyes which has led scientists to believe that they are incapable of color vision.
