Basically, feline animals see in color, but they have trouble distinguishing reds; the human counterpart being protanopia. Reds appear as differing shades of gray to a cat. It is believed both dogs and cats see mainly in grays, yellows, and blues. Honeybees and butterflies have three pigment visual receptors with true color vision within their visual spectrum. This spectrum stops short of the infrared but extends into the ultra-violet beyond human vision. Not only can these animals see in color but they can detect a mix of colors as well as pure colors.
It is believed coral reef fishes see close to the same rich spectrum of colors that humans see, as evidenced by the many colors present in a coral reef environment. Though not an iron clad assumption, the animal kingdom has evolved bright coloring to both ward off predators and attract mates – an evolutionary feature that would seem to be lost on animals that cannot see color. However, exceptions exist here too and the assumption is somewhat general and speculative.
