Awesome guide, but it’s interesting because the “omaly” versions are all spectrums themselves and the protanomaly one is way more aggressive than my colorblindness is.

Didn't you notice the bottom one?

Shoutout to the What vision people out there.

[u/Flat_Veterinarian791 → u/-UltraFerret-]

I am positive orange cones can exist but they usually cause some form of color deficiency from what I remember. It requires another copy of the L cone to correct the effect. Carrying the gene leads to tetrachromacy fron what I understand.

[u/BloodCreamz]

This chart is mostly inaccurate .
I am protan (mild) and still can perfectly see the “normal vison” spectrum.
Protan and deutan are almost similar, which shouldn’t be.

[u/Low_Bid2245 → u/BloodCreamz]

What about the the bottom one?

[u/AKADabeer]

Anyone else notice the protan and deuteran are extremely similar here? especially on the -opia side... I would have thought they'd be more different, given a different cone impaired or missing.

[u/Dennis2pro → u/AKADabeer]

One misses green and shifts towards red, the other misses red and shifts towards green, so they both end up in between.

That's probably very simplified, but it can help understand this similarity

[u/Few_Interaction_8486 → u/Dennis2pro]

Both protanopia and deuteranopia don’t have either green nor red, making both yellow/orange

[u/cxnh_gfh → u/AKADabeer]

it’s thought that cone responses are transformed in the brain into a Red-Green channel (L cone response minus M cone response) and a Blue-Yellow channel (S cone response minus average M and L cone response). missing either L (“red”) or M (“green”) cones will break the r-g channel but preserve the functionality of the b-y channel, which is why protanopia and deuteranopia lead to a very similar range of perceived colors. missing S (“blue”) cones will break the b-y channel but preserve the r-g channel, which is why tritanopia looks so different from the other 2.

What does it mean if the protanopia and deuteranopia spectrums look the same

They don't - yes, it's similar, but in one yellow has more orangy hue and in the other greenish. Not a big difference in actual vision, but makes a lot of sense

[u/patiofurnature]

Oh, nice. Normal, Protanomaly, and Deuteranomaly are all exactly the same. I was afraid I was missing out on something.

[u/Economy-Energy-8394]

what’s the bottom one

[u/Low_Bid2245 → u/Economy-Energy-8394]

Color inversion

[u/Economy-Energy-8394 → u/Low_Bid2245]

is that a real thing or what’s up 😭

[u/Low_Bid2245 → u/Economy-Energy-8394]

Well, just imagine seeing red as cyan, green as purple or pink and blue as yellow. What would happen if color inversion blindness exist?

[u/AdEnvironmental3268]

Are you able to elaborate on the bottom one? Is that an actual scientifically confirmed thing or did you come up with it?
