The rainforests in South America are being inhabited by several species of brightly colored frogs. These frogs are often poisonous and the bright colors serve as a warning to predators not to eat these frogs, because otherwise they might become sick or worse. So in this case, the information that the color conveys is very important for the survival of both the frog and the potential predator. Colors are all around us. Every object you will ever see has color and this is therefore one of the most important visual cues we have. Color conveys a lot of important information about the world around us and some of this information has interesting implications for the design of your call to actions and products.
