Apparently animals have colour vision, but most
mammals have more limited colour vision than the
humans. Dogs and cats have two "cons" of colour
vision, whereas humans have three. Most monkeys (other
than nocturnal) have colour vision similar to humans.
Birds and probably some kinds of tropical fish have
colour vision superior to that of humans.
O.K.
