If you were colour-blind, the full-colour image (top left) would look nearly identical to one of the other three.

  If you were totally colour-blind (by far the rarest sort), I suppose it would.

    I guess by totally you mean the strongest case of a particular kind of colour-blindness, not achromatopsia. Fair enough, I could have said similar. I just wanted to clarify which image is the one they should compare against. However, if colour-blindness is not so strong for most people, then these articles should depict a lesser form of colour-blindness as well, to more accurately convey the experience. I don't think I've ever seen a post on colour-blindness that did.

    It looks identical to both protonomaly and deuteranomoly simulations to me. I am colour-blind, but not 'totally' if you mean grey-scale only - just that certain shades merge together/look like the wrong colour.

      The "grey-scale" color blindness is super rare. The "just that certain shades merge together" color blindness is what usual color blindness is.

        I know, I was replying to 'if you were totally colour blind (by far the rarest sort)'.
