Cuttlefish are fascinating. From Wikipedia [0]:
"Cuttlefish are able to rapidly change the color of their skin to match their surroundings and create chromatically complex patterns, despite their inability to perceive color, through some mechanism which is not completely understood. They have been seen to have the ability to assess their surroundings and match the color, contrast and texture of the substrate even in nearly total darkness."

- danmaz74 3y agoI read that cuttlefish is actually able to perceive color even if they only have one kind of receptors on their retina. This is thanks to very oddly shaped pupils which focus different wavelenghts in different parts of the retina.
