Some animals that protect themselves with their color patterns are the chameleon, the ladybug, the gila monster, and the poison dart frog. The eastern newt is reddish-orange in color, a warning to other animals that it is highly toxic.
Some animals, such as birds, cows, and insects, are known for their ability to predict weather patterns.
not sure. n eyes there are rods and cones. most animals have only rods, which pick up light and dark but not colour. humans(and possibly some other animals)have rodsand cones. the cones pick up colour.

Animals can use colours in many different ways : Some use colour as a warning against other animals , indicating that they are poisonous/venomous so that they don't get attacked. Some animals can even mimic the colours of other animals that are poisonous to avoid being preyed upon. Some use it as a means of camouflage so that they go undetected by predators.
