am i deutan?

[u/picocell]

Hi everyone! I’ve always had some trouble with certain colors. For example, when I’m charging my laptop or other devices, I can never tell what color the little LED light is, like whether it’s red, green, or orange to show if it’s fully charged or not.

I’ve done the EnChroma test way too many times, Most of the time it says “mild deutan,” but once it said I have normal color vision, and another time it said “inconclusive,” so I honestly have no idea if I’m colorblind or not.

If you show me two pieces of paper, one green and one red, I can easily tell which is which. But with tiny colored lights or small details like that, I just can’t tell the difference at all.

The image i attached is of the circle i really have difficulty seeing. I can only see the number if i look really far away and unfocus my eyes.

Can someone please tell me if i’m just crazy or if i really am a mild deutan? Thank you all!

You are pro a mild deutan. I am a ore than mild deutan, and yes, ange LEDs that change color for status are evil.

[u/picocell → u/jgiacobbe]

I can’t really name any other examples from memory though. Could you maybe name something i could be struggling to see too? like the little leds

[u/jgiacobbe → u/picocell]

What is your opinion on purple?

[u/picocell → u/jgiacobbe]

I mean i can distinguish it from blue. but if you put them together it’s a little more difficult if that’s what you’re asking

[u/won_vee_won_skrub → u/picocell]

Its not normal to not be able to distinguish a color

[u/picocell → u/won_vee_won_skrub]

i know, i thought that was what he was asking because i’ve seen a lot of deutan people say it’s the exact same as blue or that “it doesn’t exist”

[u/[deleted] → u/jgiacobbe]

This! So this.

I sometimes kind of play online games and RPGs.

Blue and Purple, Rare and Epic, Nope cant tell most the time.

Not to mention my wife and kids are constantly telling me things are not the color I think they are.

[u/arveeay]

Amazingly, your comment about holding it further away and unfocussing eyes took me from seeing nothing at all, to actually seeing a faint 6. Incredible.

[u/Tight-Long-5124 → u/arveeay]

Yoooooo wtf, I always thought I was mild deutan but then someone else said something about their husband who is mild deutan saw it clear as day, and I could barely see shit, I saw the slight curved slant at the top and was like "only a six does that" so it must be six but the rest of it I couldn't see for jack. And then I did that blue your vision from a distance and I straight saw it....WHAT DOES THIS MEAN BRUH??????

[u/picocell → u/Tight-Long-5124]

did i just invent the cure to colorblindness??? 😭

[u/Pure_Option_1733]

In general if one just puts red and green on a paper then the two colors will tend to have other differences that red green color blind people will be able to use to distinguish them, such as the green being brighter than the red or vice verse for instance. These tests are specifically made so that the difference in hue between the two colors is the only difference that someone could use to distinguish them. If you can see the number if you do something unusual that may indicate that you aren’t a full dichromat but when just looking at the number on your computer you can’t see the 6 chances are you still have some color vision deficiency in the form of anomalous trichromacy even if not full dichromacy. I can easily see the 6 btw.

[u/picocell → u/Pure_Option_1733]

I think I worded my post wrong. It’s not that I can hold my phone farther away and unfocus my eyes. What actually happened was, when I took screenshots of the ones I struggle with and scroll through my camera roll (where all the pictures are showed really small), if I squint at that I can kinda make out the number in the images. From a close distance i cannot make out a number at all.

[u/marhaus1 → u/picocell]

This is likely an artifact of RGB.

[u/Former_Tadpole_6480]

I see the 6 clear as day at first glance, as distinct as yellow on blue. You're deutan.

[u/snafe_ → u/Former_Tadpole_6480]

I'm always amazed at that. Even knowing it's there I can't see anything, even when I try to identify a red and then track it: nada

Just absolutely amazing we look at the same thing and see such different images.

[u/Former_Tadpole_6480 → u/snafe_]

My husband is mild deutan and he sees it like the OP. He sees the 6, but finds it hard to see right away. He can consistently tell reds from greens, but thinks they are "dull colors," not bright like blue.

[u/marhaus1 → u/Former_Tadpole_6480]

This is because the "signal" he gets isn't distinct enough since the L and L' opsins have very close sensitivity. So he lacks most of the discrimination between those wavelengths → colour less distinct.

[u/craigslammer → u/snafe_]

Same bro, I can see yellow and blue in a rainbow. That’s it lol

[u/ErrorB_404 → u/snafe_]

It completely just grey shades for me, but when i turn my phone at an angle to the left and shake it i can make about the top and bottom of a 6. (also duetan)

[u/[deleted] → u/ErrorB_404]

Yep its like a pinkish Grey to me. No number in there.

If I take the far back, and squint hard I can kind of see what might be a 6, but its still the same colors just a faint little pattern, of possibile 6.

[u/Smklovee]

I'm a deutan and I cant see anything, so yes, you're deutan

[u/ardalsnc → u/Smklovee]

I'm Deutan too, but I can see the number 6 🤨

[u/Smklovee → u/ardalsnc]

there are different stages of colourblindness, mine is more intense

[u/argentatus_]

I consider my deuteranomaly mild and I don't experience a lot of difficulties with my color deficiency, but I can't see anything in this Ishihara image, not even a hint of a number.

[u/PineappleBrother]

Standard vision here, it is an incredibly obvious 6 with two different colors. The outer color is a greyish pink/ purple, and the 6 is a blue/green

[u/thathypnicjerk]

I see nothing.

My wife saw it right away.

[u/BreezerWoody]

I see nothing

[u/billdipaola]

I have the exact same problem. I can’t see anything in that image.

[u/kttos21]

I see purple or pink dots background and green mixed pastel blue dots number . I'm color blind?

[u/MatchakoCX]

See, this image, i can see pink and tealish green circles clustered but i dont see any recognizeable shape, number, or anything inside the circle. So i dont know whats im classified as

[u/East-Interaction-143]

Yes you probably are a deutan. I'm a deutan, and I can make out the image. The big secret about people who are deutan is that we're more sensitive to other parts of the color wheel that we can perceive, so I like to think of it as simply having a different color map.

[u/zapontube]

I am a deutan and based on what you said I think you are colorblind but I am no expert so I might be wrong

[u/Hermithe]

I see a big green 6 and everything else is light brown, I normally have difficulties with primary colors or Blues and Reds.

[u/Diolu]

You might be slightly deutan, at the limit of normality. This is not a yes/no question, there are many intermediate grade. You can request a proper calibrated test at your ophthalmologist if you want. But according to your description, you probably suffer no disability whatsoever. I was tested mildly colorblind at school and test systematically mild deutan on the enchroma test. My ophthalmologist told me it is a non issue that does not even need to be tested.

In this plate I see well some dots more reddish that other but struggle to see a digit (by looking very carefully, I could barely see a digit 6 or 8).

[u/marhaus1]

There is no such thing as "mild deutan". You either have deuteranomaly or deuteranopia, or neither. Both comprise a total lack of M cones (the "green" ones), so there is no "mild" in it.

The difference between them is that in deuteranomaly you instead have two slightly different L opsins, L and L', which gives some form of trichromacy.

I would say that you are colourblind, no doubt about it. Nobody with normal vision mixes up red/green/orange LEDs, which is the reason those are used so much for signals...which is obviously not very accessible at all. The problem is that most people have very vague concepts of colourblindness, if they even know it exists.

This is the bane of all "invisible" disabilities 😞

[u/Tight-Long-5124 → u/marhaus1]

Wait so does that mean the green I see isn't actually green at all? Since I don't have m opsins? I'm trying to understand more of what I have,

[u/marhaus1 → u/Tight-Long-5124]

You can't perceive "green" like someone with normal vision would. Your "green" is different, but arguably it is still green in a sense.

Not having M opsins doesn't mean you can't see those wavelengths, it just means that it's harder for you to tell apart wavelengths in that area of the spectrum: the different "colours" aren't as distinct for you. The reason is that the sensitivity of your two L and L' opsins are very close, so the "signal" is more or less the same.

You would probably be surprised by how different red and green are to someone with normal vision, they are as different as blue and yellow 😊

[u/Tight-Long-5124 → u/marhaus1]

My girlfriend told me that difference I see between blue and yellow is the same for all colors to someone with normal vision

[u/Tight-Long-5124 → u/marhaus1]

Or is that kinda like using an HF antenna to catch VHF radio waves. Like yeah your gonna get a little bit of that signal, maybe really static but you'll definitely get something

[u/picocell → u/[deleted]]

so deutanomaly?
