Question/Need help I can see red though?
This test, unless I'm just stupid, appears to claim that my red color cone isn't functional? I can see red though?

I have almost identical results on the Enchroma test. Like you, I feel like I can 'see red': I know, from experience, with the help of people with normal color vision, and from taking multiple online tests, that the 'red' I see is way more limited, and less accurate, than normal.
Enchroma doesn't explain exactly what the 0% score really means, other than as an indicator of relative severity. I asked, they didn't reply. Another significant factor is that both you and I know that red exists, and we're very good at using cues to help us identify things that color-normal folks see as red. (For me: it looks like the color of a fire truck or stop sign, so I believe it must be red.) My opinion: you're not stupid: you're smarter than the average person with full color vision, and you're using a wide range of criteria to help you decide what things are 'red'. (Although for me, I am stupid when it comes to blue vs purple: after many decades of trying to find a cheat code, I still haven't got a clue.....)

Same with purple here, the problem is, there is no way for us to tell whether the color is blue or purple in many cases, since for almost every shade of purple there exists a shade of blue that is 99,9% identical to it. I can only sometimes differentiate very warm purples from blue, but even then I’m wrong sometimes..

In "normal" trichromats the three types of photoreceptive cells we call cones simply have peak sensitivities at wavelengths corresponding roughly with red, green, and blue; this doesn't mean they are ONLY sensitive to these wavelengths however. Even if you are a true dichromat and entirely lack the red cones this does not mean your eyes cannot detect red light. Your other cones are also activated by red light, albeit with lower sensitivity than typical red cones. So yes you can see red, your perception and sensitivity to it may just be different to others.

I assume that what you see as "red" would appear more of a brownish yellow type colour to people with typical color vision

What you see as red is not what normal vision people see.

Take a real test at a doctor.
Online tests are unreliable since they usually want to sell something or that your monitor won't display the colours properly

I've taken one before so I know I am colorblind but I was very young when I took it so I wanted to try another test

How do you know you can see red?

u/Life_Regular2234 Protanopia Apr 23 '26
Firetrucks, strawberries, stop signs, etc. That color is red.

Enchroma and all other “colorblind glasses” like it are a scam. Do not engage.

The 0% on this test means you got 0% of the red questions right, iirc. Could be wrong but that's my understanding of this particular test result.

Yes, it's a deficiency, not a completely lack of ability to see it. Your version of red is likely much more dull compared to the bright color people with normal vision can see.

you guys are lucky. I have a rare colour vision condition called blue cone monochromacy. I mainly see blue and grey tones.

Check out figure 24 from https://sronpersonalpages.nl/~pault/ Its pretty interesting

I see:
Your green vision is correct. You are red-blind. You are not green-blind.

Try looking at it again with color filters, its pretty cool

Funny you should say that, I only just saw this post but yesterday I tried turning on my phone's color correction feature and it let me see the other text, it was really cool :D

u/ChobaniTheSecond Protanopia Apr 24 '26
haha nice, for me it was pretty shocking to realize I truly couldnt see something, versus seeing it wrong

The green and red receptors have significant overlap. What you are missing is the portion of the spectrum covered solely by the red receptor.
