To me this is interesting that green and red look the same with RG blindness. I'm YB blind in one eye, but I can easily tell a yellow thing isn't blue, and vice versa. It's the colours around blue and around yellow that I can't differentiate with that eye. (ie: red and orange are just red, green and blue are cyan, and dark blue or purple might as well be black. Royal purple looks like rich chocolate, so that's kinda entertaining.) So the deficient pigments seem to have very different results to colour perception.

Fun fact: I sometimes entertain myself by A/B testing between both eyes with my hand. It's especially interesting at Christmas when bright colours abound. Anyone who's ever seen me doing that probably thinks I'm a bit off, but that's okay. It will probably help with social distancing this year.
