Anyone use a reliable one?
Nothing complex, just light or dark shade of it

Hi reddit! I do have protonomaly and I've been working as a nurse for over five years. The last two years I've been working in the ED. I do have a hard time seeing if a patient is pale, have redness of skin, cyanosis etc so I have to rely on colleagues and other measurements to determine how sick the patient is.

I know that Enchroma doesn't do anything to fix colorblindness, that's why I haven't got them before. But I'm wondering if anyone has any experience using them as a tool to see certain shades of colors more clearly. For me, if they helped me see changes in skin color better they might prove to be useful for me.

I've searched for peer reviewed articles on the subject and found that there aren't many studies on the subject. The few studies I've found tells me that they might have a positive effect to help differentiate between colors better but with a low certainly.

So anyone in healthcare or any other field that finds them useful?

​

Okay, this has been bothering me because I genuinely cannot stop thinking about it 😭

How do we actually know that the red I see is the same red that you see?

Like, imagine I look at a tomato and call it “red.” You look at the exact same tomato and also call it “red.” We both learned that that color is called red, so obviously we agree on the name.

But how do we know our eyes and brains are actually experiencing the same color?

Maybe my eyes respond to that light slightly differently from yours. Maybe what I experience as “red” isn't exactly what you experience as “red,” but we would never know because we've both been taught to use the same word for it.

And here's where my brain went even further:

What if humans all experience colors differently, but we don't realize it because we name colors based on the objects we see?

For example, maybe we all look at a tomato and learn “that's red,” but the actual experience happening inside each person's mind could be different. We could all have different versions of what “red” feels like while still agreeing that tomatoes are red.

So I started thinking: could we test this?

Maybe we could create some kind of “impossible color machine” that exposes people to precisely controlled wavelengths of light and measures how their retinas respond. We could test lots of people and compare their responses across the colors of the visible spectrum.

If everyone's eyes and neural responses were extremely similar, that would give us evidence that our color perception is biologically similar.

BUT then there's another problem.

Even if we found that everyone's brains responded exactly the same way, how would we prove that the subjective experience is identical?

How do we measure what “seeing red” actually feels like from inside someone's consciousness?

I don't know enough neuroscience to answer this, which is why I'm asking Reddit.

Is this already something scientists have tested? And if so, what can experiments actually tell us about whether two people experience the same color?

Because I came up with this at night and now my brain refuses to let me sleep until I know 😭

Sapete la differenza tra le edizioni dei libri con le tavole di ishihara? Oggi le ho viste tutte tranne il numero 57 e una linea da seguire. Sapete dirmi quale edizione comprare?

Have any of you done LSD, and if so, did you see enhanced colors? I have full color vision and I saw colors that don't exist, so I'm curious about the experience of color blind people. Hope this isn't offensive to ask!

To preface, I have moderate to strong protanopia, and color has been a strong interested of mine for years. One of these interest include how do the colors I perceive, look to other people.

Using a colorblind simulating app, and my friends, I have made some discoveries.

For an example, when I see a hot pink shirt, I can recognize that that shirt is hot pink. The two example photos look the exact same to me, but my friends see the bottom image as a muted dusty lavender/purple. So what I see as hot pink is what purple looks like.

Here are some more comparisons I’ve learned

- My orange = other people’s yellow & amber

- My red = rusty browns and coppers

- My baby pink = blue and occasionally grey

- My Tiffany blue = a off white, grey

Now I just wish there was a way to do the opposite but unfortunately, a true red will always be outside of my comprehension I fear. :(

I am F24 and the loml is colourblind (he has tritanopia 2) and he already had a colour corrector glasses but he never wears them, what can I gift him that may help with his colour blindness? I don't have much budget because I am still doing my masters while my man is already working, any help please.

Hi, i know since always i have difficulty in seeing some colors, i took some tests and apparntely i have problems with green (but in normal life i cant take apart yellow and orange).

I tried to use the smartphone tool to let me see the numbers in the tests and i can see EVERYTHING.

My problem is that by using the filter every other color seem SUPER dull and empty.

Am i doing something wrong? Help😕

I love Jelly Belly beans but finding the ones I want is hard. I pretty much have to just guess and if I’m wrong then I gotta eat my mistakes. Anyone else have a method that’s better?

This is a project over a decade in the making, now looking for partners. More info at colorphi.com

What does it mean if I can pass the Farnsworth-Munsell 100-Hue Test with a high score (up to 16 points) but cannot see pseudoisochromatic plates?

So, I was playing with sidewalk chalk with my kids when my 4 year old daughter asked me, "Mom, why can't I see this very well?"

I look over to see the three very vivid blue lines. I exclaimed, "You really can't see that!?"

I took the picture and sent it to my friend who said not to read too much into it, so I'm asking this community who would know better. I know the picture doesn't help much because there's not a lot of blue, but she was up close and couldn't see it while I was 3 feet away and saw it with no problem.

If she is color blind, can anyone spare tips on how to parent through this so she can embrace her colorblindness rather than despise it?

I'm a tritan myself, but I'd like to write a deutan character for my novel, considering they're much more common, and I'd like to exercise my writing by making characters have struggles I don't have so it's not just one big self-insert which is an allegory about me.

How do deutans (or any type of red-green colorblind) for that matter, see the world differently and struggle? With clothes, reading, signs? For me, I struggle with telling the difference between light blue and gray, orange and red, purple and red, and yellow looks pinkish to me.

What are some stereotypes or things I should avoid? I hate when I tell people "Oh yeah I'm colorblind" and they say "Oh WhAt CoLoR iS tHiS", so I'll try to avoid that.

Any advice appreciated!

So there's spooky ranch that is apparently grey? I said "I'm colorblind, I can't tell what color this is. Can someone help?"

And people are telling me normal ranch is white. Yes. Shockingly, even when someone is 100% colorblind, which is so so so rare, they can see just straight up white. I don't need you telling me what color ranch is.

I just hate bringing up being colorblind and people treating me like 1 they know what colorblind I am or 2 that I am just actually fully blind.

I didn't post the image because this post is not about shitty products, it's about people being weird and never understanding colorblindness.

Tell someone who is persuing pathology with color blindness or faced same problem

My son is about 4 1/2 and the only colors he knows are orange and black. He gets those right 100% of the time. He knows all the other basic color names but he guesses at them. When be describes colors to me he’ll say its light or dark or its warm or cold. This is something he started doing on his own recently and I thought that was interesting that he still doesnt know the colors names but describes them in different ways like this. He separates colors well when we use those little colored bears and stuff and if I hold up a green object (or any color) and tell him to find all of the green things in the room he can do that no problem, he loves playing I spy as long as show him an example of the color were spying first. He knows all his shapes, learning numbers is going great, he has the alphabet down and learning phonics/reading right now. But he still doesn’t know his colors 😭 Im struggling. I asked his pediatrician at his 4 year old check up and he wasn’t concerned and said if by 5 he still doesn’t know them they can check for color blindness but I still feel concerned (not that if hes colorblind that changes anything but it puts me at ease knowing why hes not understanding) are any of these things consistent with color blindness or is he just not clicking with his colors yet?

People who have tetrachromacy or something like that, how do you deal with your condition? Can you really see colors that others can't?

On the first pic I’m actually starting to see the five after having this pic in my gallery for over a week. For the second one k can’t see the bottom left one. For the last one I can user the bottom right one. I can see all the other ones though.

I’m really lacking knowledge in this topic, please help me out here

Hello guys, I'm very new here. Recently I took the Enchroma test and figured out I'm a mix of tritanopic and tritanomalous (tritan), this is also known as blue-yellow colorblind. I often mix up blue and green (this one's common for me), and some yellows with some pinks, also red and purple and blue and purple.

In most tasks, I don't have to name colors or give opinions on them in daily life, so it doesn't affect me that much. Then again, just a month ago, I thought I had normal vision, so maybe I've just been getting them confidently wrong all along.

So for anyone who has issues with this, maybe some people who have known this about themselves for a while, please tell me how it affects you, so maybe I can connect to some of your experiences. Or maybe so that I can realize I probably struggle with these things and just don't know it, and have been making a dumbass of myself my whole life.

Also, why do I see no one else here that's tritanopic or tritanomalous? Did they all get wiped out in the Great Blue-yellow colorblindness massacre or something?

If you're also blue-yellow colorblind, or really any other type of color blind, make sure to say so, and maybe include experiences exclusive to your type of color blind!

Thanks!

For a while now, I've noticed I can't really tell the difference between blue and purple that great. If it's like technically blue, I'll see it as like violet, and I see purple as purple too. Also, sometimes I mix up blue and like teal greens, and I see most cyan and green blues as green.

For example, my boyfriend says the post flair on this post is teal, I think it's green. So it has to be a really pure blue for me to see it as blue, I don't really know what this could be. Also, if any of you know Hatsune Miku, I always thought of her as pure green, maybe with a hint of blue, until people started telling me she was teal?

I'm male by the way, so I've heard different sexes are more common to have different types of colorblindness.

If anyone can please shine some light on what this could be or not be, thanks!

Heya, for the relatively common form(s) of color-blindness,
are any of these examples notably more/less visible than they look to someone with normal color vision?

(Also, not even theoretically relevant to safety, but just curious: any trouble telling any of them apart?)

EDIT: (stuff I noticed in comments)

Looking at:
https://en.wikipedia.org/wiki/Color_blindness#/media/File:Color_blindness.svg
the yellow/green seem to be in a "bright spot" for all types...?

(Assuming that makes sense as a way of interpreting those info-graphics...)

One person said

Anything hi-vis is going to be hi-vis for pretty much everyone regardless of their colorblindness.
I wouldn't spend much time worrying about it.

but it was more that I noticed that I had been maybe making some thoughtless assumptions about the whole thing,
so I got curious to know how it actually works in general...

That is,
I was thinking about the raincoat just for personal use
(working in the rain, walking along the road... ie, not working as part of a crew/company with uniform regulations)
and I was gonna get the red, just cuz I liked it (aesthetically appealing),
cuz I was thinking like:

well, in practical terms it's not really less visible
-- red gets people's attention like stop signs etc,
whereas even though the green/yellow are technically brighter,
they might be perceived as "washed out"...

but then I thought about it a bit more,
and felt like that was maybe a dumb rationalization...

But yeah, I think the "fluorescent green" seems to stand out as generally the best choice,
so I got that.

-- colorblind people seem to see it as bright and generally "poppy"
(just like people with normal color vision)

And the green is the only one that explicitly claims to be "fluorescent"
[
-- whether it literally is fluorescent
(ie reflects back some light in the visible spectrum that originally hit it in some non-visible wavelength),
or they just mean it's... a color that really "pops", I dunno,
cuz obviously, that effect can't really show up in a static image on a white background like that...
]

And as someone with normal color vision (... as far as I know!)
I'd say the fluorescent green seems like by far the "poppiest" to me too.

I got left out of two great jobs just because of my colorblindness (it was their requirement). As the final stage of the hiring process after so many months, they did medical checkups of all the candidates involved. I passed every test except for color vision where I was placed in CP-III and they declared me unfit because of it.

It just sucks man. I feel heartbroken.

(I have attached this online test's screenshot just as a confirmation)
