You wanna know some impressive shit? The Cuttlefish is colorblind, and yet despite that it can change its colors PERFECTLY to mimic its surroundings.
IT CAN EVEN DO THIS IN TOTAL DARKNESS
HOW THE FUCK
Just like Daredevil, they can probably feel the vibrations of different color textures via sound waves or some other bullshit.
Oh the truth is even more bullshit than that, if recent deductions are correct:

Because every color is a different wavelength, it’s possible to have a lens focused in such a way that only one color at a time is clear and others are blurry.
So it seems that the eyes of cephalopods rapidly “sweep” across every possible level of focus. It might all look like different shades of grey to them, but in just an instant, their powerful brain registers exactly which shades of grey come clear at exactly which levels of focus and tells the skin which chromatophores to switch on and off to match that shade as close as possible.
