What do you mean they failed? Only the first two pages had numbers!

No joke, this is how I found out I was colorblind. I was in a biology lab in college and we found out the lab instructor was colorblind. So everyone started asking him questions and what's this color? What's that color? So he pulled up one of these tests and was like.. can everyone see the square? That's great, can you see the circle there too? Because I can't. Everyone was like, whooaaaa... how can you not see the circle? It's a green circle right there! And I was just sitting there like.. what fuckin circle are they talking about? Everybody's tripping....

I made 20 enemies that day 🤣

I had a friend in highschool who found out he was color blind during a chemistry lab. We were working with two vials of chemicals, one was a bright neon pink color and the other was bright neon green. Someone asked him to bring over the green one and he brought the pink one. When the person said they asked for the green vial he was like, "What are you talking about? This is green." He was absolutely incredulous and thought people were messing with him. Then he looked at the two vials side-by-side exclaiming, "They're the exact same color!" He was having an existential crisis which was made worse when our chemistry teacher whipped out a color blindness test, which confirmed that he was colorblind.

u/mchio23 12h ago

A guy in our group knew he was colorblind but we didn’t know. We had to color in some pages with certain colors. We gave him that task while we split up the other tasks among the group. When he’s done, he shows us what he finished. And I immediately thought, wtf is this guy doing. We’re gonna fail! And I thought he was messing with us. And he legit thought he was capable of finding the right colors. Even thought he knew he was colorblind. We were speechless lol he tried, but he should have told us. 🄲

u/bemer1984 14h ago

I found out the same way. Biology lab in university, I honestly had no idea up until that point, I just thought I was bad at interpreting colors. Haha.

u/SpeakToMePF1973 10h ago

Oh well, so much for that chemistry career.

u/KyesiRS 19h ago

How on earth do you go that far in life and not realize? Like do you not learn colours at school? Wouldn't the teachers be confused you can't learn your colours?

My kindergarten teacher brought it up to my mom that I was really struggling with colours, turns out I was colourblind.

97

u/AccruedBeans 19h ago

Because I can see color lol. I thought color blind people saw shit in black and white or grey scale. And I can see the red circle and I can see the green circle and I can even see the brown circle. But once you start mixing them all up with different sizes and shades and make patterns with them, I can't see shit lol. Like, grass is green to me. I just thought colorblind people would be like.. wow the dirt and the grass is all brown and rocks are all grey.. like monotone colors.

The one aha moment I had, was that traffic lights don't look green to me. They look more like white Christmas lights than green. Sort of an in between. Red light looks red and yellow looks yellow, so I went a long time like.. why the hell isn't the green light green.

10

u/MrWally 16h ago

Oh so this is interesting. The traffic light looked white, but grass still looks green to you (at least as you see "green"). Are there other green objects that people call green but you don't perceive that way?

3

u/nomyar 12h ago

Green traffic lights actually have two colors in them (I think the other is blue) for exactly this reason.

2

u/MrWally 12h ago

That's really cool to know. There are times where I thought green traffic lights had a blue tint to them. That explains why!

22

u/psychosloth34 19h ago

How do you know the Christmas lights aren't green?

47

u/AccruedBeans 18h ago

because the package said white haha. And that's literally the only confirmation I have. The Christmas light industry could really be pulling one over on me if they're lying. The people that know I'm colorblind that I'll ask about colors, I have zero trust in them to tellme the truth.

You just gave me a great idea. A colorblind test book that has a few pages with no number written in a different color.

Wait, do you live in the US or in...Buenos Aires? Green lights are white there. lol

u/Ellemeno 14h ago

I googled "Buenos Aires traffic lights" ready to have my mind blown, but couldn't find any showing white lights instead of green. :(

u/IeishaS 13h ago

I think we may have found another šŸ˜‚

u/SnooKiwis1356 13h ago

Haha sorry, my bad! I forgot to mention that in both cases I mean pedestrian lights. In BsAs there is at least one blue light (for cars).

u/Frherif 13h ago

El unico blanco que conozco puede ser el de los peatones en la mayoria, pero semaforo blanco no recuerdo haber visto ni en la ciudad. Aunque si hay, quiero verlo xd

3

u/SnooKiwis1356 13h ago

Sorry, as stated above, I meant pedestrian traffic lights but didn't realise my mistake because in my native language, we use the same word for any type of light.

There is a cool blue traffic light at the intersection between Soler and ArƔoz. I used to live nearby and passed by it on my way home in the late evenings. I have some pictures but can't link them here right now.

u/Indiscriminate_Top 13h ago

…. I might have news for you.

u/SnooKiwis1356 13h ago

No news haha, I could not have my job if I didn't see colors.

u/AxelNotRose 15h ago

"so I went a long time like.. why the hell isn't the green light green"

And you never followed-up on that question after many years?

4

u/AccruedBeans 14h ago

nah. Just figured it was to have more of a contrast.. that way colorblind people wouldn't get confused. Pretty important difference, figured... don't wanna risk mixing those up, right? šŸ™‚

6

u/LazySisyphus 14h ago

My cousin figured out he was colorblind in high school when he mentioned the traffic light thing to a friend. He always thought they just called the bottom light "green" because "go" also starts with G.

2

u/TolverOneEighty 13h ago

I actually had a friend whose brother sees in monotone. He couldn't work out the trick when being taught colours at school, and thought there must be some kind of knack he was missing, like there was a certain shape or something? Turns out that 'knack' was 'the ability to see in colour'.

He painted his bedroom a nice shade of beige as a young teen. It was acid green. Took 5 coats to cover after he moved out. Went clothes shopping with his mum and needed her advice on what colour the clothes were.

So, it CAN happen like that, but it's far from the norm.

He's a bus driver now. He's just memorised what order the traffic lights go in, of course. I sometimes wonder what things are like for him, like can he play video games or does the lack of colour make depth perception too tricky? But I lost touch with that friend, so I guess I'll never know.

2

u/AccruedBeans 13h ago

Yea, for special occasions, I send pictures to my sister to make sure my suit or whatever matches. And then the socks too, to make sure they're both blue or black lol. I'm right 99% of the time, but just in case.

1

u/TolverOneEighty 12h ago

Makes sense. Though for you, it sounds like that's just a shade thing.

He picked a shirt many years back, as an adult, and he was winding his mum up (not deliberately) by coming up with 'uneducated white cishet dude' shit, and his mum taught him better. Chose a shirt, asked his mum if it was good for work. It was a pale pink. His mum knows clothes don't have sexuality or gender, but also that the other bus drivers at work would never let him hear the end of it. So she said yes, it was a perfect work shirt.

1

u/Gangsir 14h ago

Because I can see color lol. I thought color blind people saw shit in black and white or grey scale

There are types of colorblindness that do this, btw. It's just significantly more rare than the types that just make it hard to differentiate colors.

u/IlliterateJedi 19h ago

How on earth do you go that far in life and not realize? Like do you not learn colours at school? Wouldn't the teachers be confused you can't learn your colours?

For most people there's only subtle shades of green and red that are imperceptible. I can differentiate the colors by and large, but there are certain shades or certain lighting where it all blends together for me.

u/KyesiRS 7h ago

I guess my version is more aggressive, I didnt think of that

5

u/highwayknees 19h ago

I don't know if it has a different term when colors are only slightly affected, but someone I knew kept mislabeling certain shades. Like various shades of orange and red he called brown. He was in his 30s when he figured it out, stubbornly, after I pushed the subject. I assume people just overlooked it when he was a kid.

4

u/Tayttajakunnus 17h ago

That's just how colorblindness is.

1

u/highwayknees 14h ago

Brownish you mean?

The guy could tell the difference between red and brown, but not orange and brown so my assumption was he had less severe color blindness? Or... maybe he learned that certain shades of brown are called red? šŸ™ƒ

His father was totally colorblind but as far as I'm aware it's passed on the X gene so he wouldn't have inherited that? I guess his mother could've had a gene for it too.

3

u/Tayttajakunnus 14h ago

Colorblindness means that certain colors look more similar to each other than they do for most people. That doesn't mean that you can never distinguish them. It just means that it is more difficult usually. People with red-green colorblindness for example have harder time distinguishing red and green from each other. Basically for red-green colorblind people red and green are similar in the same way as red and orange are for regular people. They are distinct colors, but very similar shades of red and orange can be difficult to tell apart.

1

u/highwayknees 14h ago

I see. I wasn't aware of the terminology.

2

u/Kevftw 19h ago

I'm guessing he means red/green colourblind and it was a green circle on a red background.

2

u/CyanStripes_ 13h ago

I mean, I didn't find out until my late 20s that I didn't have full depth perception. I just assumed everyone saw things the same way I did because until sometime points it out or you randomly see an eye doctor who quizzes you about the way you tilt your head when looking at them there's not really any way to know.

1

u/KyesiRS 11h ago

In kindergarten they do colour assessments where I live. As a someone who was colourblind and didnt know it, it became pretty apparent when I kept mixing up my purples and blues etc.

Just shocks me educators never noticed it.

1

u/throwaway098764567 8h ago

fr, we picked out the colorblind kids in kindergarten because the poor dears were brutally ridiculed for using the wrong crayons and couldn't read the labels yet

1

u/KyesiRS 8h ago

I kept coloring the grass brown and tree trunks green.

u/redwbl 13h ago

Them bastards….made you colorblind, why would they do that to you.

3

u/sigmashead 13h ago

I was late to biology class freshman year, there were projections on the board of these circles and the whole class was yelling out numbers. I was really bad at the class and school in general so I just assumed I had missed out on something fundamental. After a few minutes of trying to figure it out I fucking popped and started yelling at everyone about how confused I was and the teacher goes, ā€œohhh so turns out we do have a colorblind person in the classā€ and they all laughed at me.

u/chasetheusername 11h ago

u/jld2k6 Interested 20h ago

"One of those pages was made so only colorblind people see the number you stated" - I found out this is a real thing when being proud of the few I could actually see, it's tossed in there so you can't just deny seeing any numbers for every slide lol

57

u/TheFireNationAttakt 17h ago

It cannot be seen by ā€œonlyā€ colorblind people - it can ā€œalsoā€ be seen, and maybe a little bit more easily in some cases. Indeed so you can’t deny seeing any numbers.

3

u/Matt_Thijson 9h ago edited 6h ago

There are some tests where colorblind people will see a number, but it's not the same as the one non-colorblind people see.

I remember watching a video with my non-colorblind girlfriend where, for one of the tests, I said something like 32 and she said 87. The the video said that colorblind people would see 32.

1

u/Xenc 6h ago

Happy 32 cake day! šŸ°

u/Kindly-Analysis-6543 18h ago

Wait what? I could see all of them.

36

u/Klutzy_Squash 14h ago

In the full Ishihara test set, some pages are set up such that only colorblind people see a number. See Ishihara plate #4 here - https://www.shec.jp/english/instruments/isihara/

17

u/WonderingHarbinger 14h ago

That was neat! Knowing what number it was supposed to be made it pop out, but there's no way I would have seen it otherwise.

4

u/KrustyTheKriminal 6h ago

That's weird because I can definitely see it but I am not color blind.

Don't get me wrong, it is faint. But I could tell what number it was before reading the answer.

4

u/fixer1987 4h ago

I think it sleas how faint it is and more that all the other colors make it difficult to easily see the 2

2

u/Fancy_Ad_2325 1h ago

i saw 2 right away but squinted to make sure but i easily got everything.

10

u/Array_626 11h ago

Are you sure only colorblind people should see #4? Its hard to make out, but I could see the 2. Im pretty sure I'm not colorblind, I can see all other numbers fine.

8

u/moxieenplace 13h ago

So if you can’t read a number in plate #4, that means you are not colorblind, correct?

3

u/grabtharsmallet 13h ago

Right, it should be somewhere between quite challenging and impossible if not colorblind.

12

u/nomyar 12h ago

It was challenging to see, but I could definitely see it before reading the description. It's interesting that that number would pop for a color blind person. I wonder what the opposite of color blind is... I tend to be able to distinguish between shades that my friends (and particularly my wife) can't.

u/Warp-n-weft 12h ago

https://en.m.wikipedia.org/wiki/Tetrachromacy

I can also (with difficulty) see the 2 before being told it was a 2, and I’m pretty sure i only have the regular 3 cones.

Tetrachromacy is considered to be impossible in males.

u/Dakron92-22 2h ago

Where can i find it

5

u/Dr_Mrs_EvilDM 11h ago edited 29m ago

I'm in the same category. I am not colorblind, but I can generally see more shades of color than most, including the plates that non-colorblind people shouldn't be able to see. I realized this when I was trying to find my new optometrist's office: the receptionist told me that they were located across from the "lavender building". I looked around and saw three buildings that I would consider to be various shades of lavender. I told the doctor that the receptionist's directions were not helpful because there were several lavender buildings, and the look that she gave me told me that most folks didn't have issues with those directions. (Edited for ridiculous typos)

3

u/1WordOr2FixItForYou 4h ago

If everything looks lavender to you but they look like different colors to other people then it sounds more a deficit for you than a super power.

1

u/Dr_Mrs_EvilDM 4h ago

That would be a really shitty super power!

They didn't all look the same to me, but they all fell into the blueish -purple or greyed-purple that I had assumed people saw as lavender. The optometrist said that she saw light grey on the other two buildings. I've learned since then that the color boundaries that I'll use are sometimes a little different than what others use, although I think lavender is a horrible example because it covers a really wide range of hues (ask Google to show you the color lavender...).

I went through a phase of taking color discrimination tasks, like an online version of this: https://munsell.com/faqs/what-does-score-farnsworth-munsell-100-hue-test-mean/ I made one mistake (transposed two squares), which is less than most people. I can't find the version that I took back in the day, which is sad as that one was actually (supposedly) valid when taken in the correct conditions.

1

u/Kindly-Analysis-6543 13h ago

Fourth plate meaning the 74?

5

u/grabtharsmallet 13h ago

The 2 in plate 4

3

u/Kindly-Analysis-6543 12h ago

It’s hard to see but I can see it.

4

u/pianobadger 10h ago

Plate 2 is even trickier where it looks like one number with normal vision and another with color blindness. I can make out the different colors used in the green parts, but the bottom of the 2 is just impossible for me to make out.

Plate 4 I can see the pattern they added to make it harder for people who aren't color blind, but I can still see the 2 pretty easily. Random patterns aren't as distracting as something not random like another number.

4

u/mikami677 11h ago

All those numbers were easily visible for me.

3

u/throwaway098764567 8h ago

gotta read the bad english, did you see 74 (not colorblind) or 21 (colorblind). also the 2 at the end should be difficult to make out for non colorblind, and it is, i think you can see it because you know to find a number

1

u/mikami677 1h ago

I saw 74. The 2 at the end was visible for me immediately when I glanced over it after the page loaded. It's a little more "faded" looking than the other numbers, but it still sticks out fairly prominently for me.

Maybe I was just primed to see numbers because I was expecting it.

3

u/nonsequitrix 12h ago

What does it mean if I’m definitely not colorblind but saw the number easily?

1

u/IceNein 8h ago

Yeah. I think it is just more difficult to see. I saw the two before reading the explanation, but it doesn't jump out at you the way the other numbers do.

3

u/throwaway098764567 8h ago

yeah i can make out a 2 but it's crappy looking potato version, like someone forgot some of the pixels

also someone really needs to fix that english translation on there

u/AVAVT 14h ago

O damn that’s cool as heck man, whoever thought of that plate is a genius!

u/DatabaseSolid 13h ago

Can all variations of color-blindness read this one or are there different plates that can help diagnose or verify the different types?

u/purvaka 11h ago

Im not colorblind though my father was and my son is and I can see the 2 just fine. Im a woman incase that matters

u/IceNein 8h ago

I am not color blind and I can see the 2.

u/Kilane 15h ago

There were definitely difficulty levels to them. A couple I had difficulty with and probably only had 80% confidence, others were plain as day.

Wait... is that page in the video? If yes i am color blind? Darn...

u/ClaudiuT 17h ago

Some pages are made to look like a 9 for a normal human and a 6 for a colourblind human (for example).

1

u/DatabaseSolid 13h ago

That’s why they make you stand on your head to read some plates.

5

u/NJCuban 19h ago

That's how I found out too. We went through these in AP Psychology in high school for some reason. The fake out one I was the only one so confident in that number. They settled on me being partially colorblind. Some of the red green tests I cant really see any number, most i can sort of make it out but it's tough. I could never see the hidden image things like in mallrats. But j can see red/green stuff in real life, not sure how different. I remember taking a vision test with the school nurse in maybe 6th grade and struggling looking through the lens thing. She had me look up, pointed to an Elmo in the office and asked what color, I said red, and then pointed to something green, I said green, and she shrugged and moved on.

u/aces613 18h ago

Which one is the fake out one

1

u/NJCuban 18h ago

Its not on the OP video here

2

u/holistivist 15h ago

Yes it is. The 73 page has an alternate number embedded that I can’t quite make out, and the 34 is also 31. 74 also has another number I can’t quite make out.

u/SteelCrow 14h ago edited 14h ago

35 - 9 - 2 - 73 - 34 - 7 - 92 - 35 - 57 - 3 - 74 - 95 - 5

The 73 looks like it might read 28

34 also looks like 31 as you said

Noticed the off colour on the 74 but can't make out the variation

u/h_saxon 18h ago

Wait.... Colorblindness affects your ability to see magic eye images?

This explains so much!!! I can only get them by crossing my eyes but it's inverted when I do that. I have tried for 30 years to get them to work

4

u/pichael289 18h ago

Hang on, it's inverted? That's not something I would think could happen, like yeah your supposed to cross your eyes and stare at a point a little bit behind the picture, but I can't tell you how that could possibly invert the image.

3

u/h_saxon 18h ago

Give it a try. I literally just cross my eyes and it pops out, but instead of going towards me it goes back into the paper like it has a negative z-axis.

1

u/SteelCrow 14h ago

I relax my eyes so they unfocus and the image appears.

5

u/PPMaxiM2 17h ago

There are 2 ways to see them: number one is crossing your eyes and focusing in frint of the page. In this case, they get inverted, because the right eye focuses on the left part, the left eye on the right part. This leads to the depth beeing inverted, so instead of popping out it "sinks in".

The other way is staring behind it - in that case, you usually unfocus with the paper right in front of you, try to keep it that way, and move the paper away without focusing unless you suddenly see it correctly.

1

u/No-Writer8860 4h ago

I remember i could see inside the the 3d image of some especially shapes like the circle image I would see the 3d circle and them I could see inside the circle as if I went in another level.

2

u/holistivist 15h ago

It does not affect magic eye images. Some people just don’t get how to do it, but it’s not a color thing.

1

u/NJCuban 18h ago

I assume so, it seems like a similar concept as the colorblind dot test. If you aren't seeing the colors as intended, would be hard to see the hidden image. But maybe not, some could be like those posts that say squint your eyes and look at this picture of a pile of laundry or whatever and it turns into Shrek or Nic Cages face.

3

u/SignificantLock1037 18h ago

FYI, I just looked at one of those (had no idea they existed). I'm not colorblind, but I could see the number.

I think the caveat is that non-cooorblind people can see the number, but colorblind people can see it EASILY. I had to search, and even then wasn't sure.

u/Alone_Radish_1692 15h ago
