dark red
-- It depends on the species of squid and also how they are feeling. Squid have chromatophores that they use to change their colour. Deep sea squid are generally dark red (the red wavelength doesn't penetrate into the deep sea, making them nearly invisible) or delicate and clear. The firefly squid has blue bioluminescent chromatophores that it uses to lure prey, signal to other squid, and avoid predators by blending in with the surface ocean. When squid are calm, they are typically a light sandy colour, but if they feel threatened or are trying to ward off competitors they are often a bright red. Some are striped, polka dotted, and they come in every colour. There is not single distinct colour that squid in general are. --
