Pigmentation is a biological process by which cells synthesize, package, and distribute pigments that confer color to tissues, organs, or whole organisms, typically via specialized cells such as melanocytes, chromatophores, or pigment-containing plastids. It involves regulated pathways of pigment biosynthesis (e.g., melanin, carotenoids, ommochromes), intracellular transport and sequestration within organelles, and spatial-temporal control of pigment cell differentiation and activity. Pigmentation contributes to photoprotection, camouflage, signaling, and physiological regulation, and is modulated by genetic programs, developmental cues, endocrine factors, and environmental variables such as light exposure, temperature, and nutrient availability.
The animal world is incredibly colorful, and behind this color palette is a constant game of survival.
