The wasp has a banded colouration of black and yellow. Certain poisonous tree frogs have bright colouration. There are caterpillars that are also brightly coloured, and often sporting irritating hairs, or have a horrible taste. All are examples of warning colouration that predators will associate (once tried) with something best to avoid in the future.
Coloration is not a behavior, it is an adaptation. Warning coloration is an example of defensive behavior.

Aposematic coloration (also known as warning coloration) is the conspicuous coloration of some animals, such as skunks and poison arrow frogs, that serves to warn potential predators of the harm that would come from eating the animal.
The lionfish has a couple of special adaptations that help it to survive. One is its coloration, which serves as a warning to those that would attack it. The other is the poison this fish carries in its barbs, which can sicken or kill a would-be predator that doesn't heed the warning of its coloration.
Different types of adaptation are counteracting behavior, camoflauge, warning coloration, mimicry, and chemical warfare.
