Animals that change colors for camouflage often do so to match their background colors for blending into the environment, evading predators, or surprising prey. These color changes are not directly affected by or related to colorblindness in animals. While some creatures may have limited color perception, their coloration changes usually come from physiological changes to pigments in their skin as controlled by other mechanisms in response to various external cues such as environmental lighting. These color-changing abilities generally do not depend on specific color perception capabilities to function effectively.
