What are some ways animals use colours?
Answer 1:

The use of color helps the animal to hide, to deceive or to attract attention.

Animals hide by using camouflage. They have colors that blend into their surroundings and they can conceal from predators.
Some wildlife uses spots or stripes as disruptive coloration. This means that the coloration disrupts the outline of the animal and helps to confuse the predator.
Some animals have bright colors to warn other animals that they are poisonous. At the same time there are animals that use these warning colors for mimicry. Since the color is similar it offers protection to the harmless animal.
While some animals use colors to warn, other animals use bright color to attract a mate and to identify another.

Good examples for these different uses of colors can be found at
