Dichromatism

Dichromatism is a property of some animals that have two different colors or patterns on their bodies, often serving purposes like camouflage, communication, or attracting mates. Unlike species with multiple colors, dichromatic animals display two distinct shades or markings, which can help them blend into their environment or signal specific behaviors. For example, some fish or insects show two prominent colors that stand out to others of their species or help them evade predators. This trait is a natural variation in coloration that plays a role in their survival and interactions in their environment.
