What colors can an ocotupus change to?

An octopus can change to a wide range of colors, including shades of brown, red, blue, green, and yellow. This ability is due to specialized cells in their skin called chromatophores, which contain different pigments and can expand or contract to alter their appearance. Additionally, some species can display patterns and textures to blend in with their surroundings for camouflage or communication. This remarkable adaptability helps octopuses evade predators and interact with other marine life.
