What does it mean to be partially red-green colobrlind? Isn't it the case that you either have the red-green cone or you don't?

- nitrogen 11y agoIt's conceivable that a mutation in the gene for the red or green light-sensing protein gets a mutation that just shifts its sensitive wavelength closer to the other. So "partial" r/g colorblindness could occur if there was still some separation between those wavelengths, but not as much as is typical.
- deckar01 11y ago> Deuteranomaly ... The medium-wavelength pigment is shifted towards the red end of the spectrum resulting in a reduction in sensitivity to the green area of the spectrum. [0] The closer the spectrum perceived by the M (green) cone is to L (red) cone, the harder is is to differentiate red from green.

- ajuc 11y agoI don't know how it works, but I have it - I can see red and green and pink in big blobs, but when there's lots of small red and green (or pink) details mixed - they seem the same to me (if their darkness is similar). Also I have problems with big uniform colour areas it there's small amount of green mixed with pink or red and vice-versa. I was making a sunset skybox for a game, and friends were wondering why the sky is slightly green - for me it was pinkish-red-yellow, but I put there some green by mistake.
- such_a_casual 11y agoThat sounds like standard red-green colorblindness.
- ajuc 11y agoGood to know, I thought standard red-green color blindness is when you don't recognize these colors at all.
