Colorblind cure comming in 5 years? Also tetrachromat vision possible?

Question

I read articles about a cure for colorblindness and giving trichromats tetrachromatic vision! It involves injecting harmless viruses with gene code for different color pigment cones. They will then grow on your retina and youll be able to see a wider range of colors! Dichromats see only 3 or 4 colors on a rainbow(brown, yellow, blue, sometimes gray) Trichromats see 6 or 7 colors(red, orange, yellow, green, blue, violet/purple) while tetrachromats may see 9, 10 or even more colors!(crimson, red, magenta, bronze, orange, yellow, lime, emerald, green, teal, blue, cyan, purple and often they see colors that aren't even named and can only be aproximated to a similar named color) I heard that there is almost as big a difference from 3 to 4 cones as there is from 2 to 3. Who here is colorblind and wants a cure? Who here wants to be tetrachromatic? I do! I love colors!

Answer 1

I don't think it is possible but it is indeed something that will be a blessing for the color blind. Ryan's references are not from leading medical journals though, all the best
