This is a fantastic thread - I've just read it from the beginning and am astonished to see that it started quite some time ago. Thanks to the OP, Dr Q, for initiating an extraordinarily interesting (and illuminating) thread. I'm not colour blind (apart from having some slight difficulty distinguishing between navy and black on a dark winter's morning by artificial light). Great thread.

On the most recent image contrast, I could make out red lines on the second image but could not see what they were supposed to be.

Cheers and good luck

Yeah, it should be easy to see the shapes with normal vision.
This is most interesting.

I am not color blind based upon aviation related detailed examinations. In those tests, almost every shape or number pops right out to me like black and white.

However, using this poster, most objects and numbers do not pop out at me, and some I cannot see without really concentrating and looking at the black and white version first. Weird.

Do you two belong in the list of color blind MacRumors members, or does the second image not work for some people with full color vision? Based on the comments here, I just added northy124 to the list.
Not sure. According to this and this, I'm color blind.

But in the following images, i can clearly tell the difference between examples.

In the first image in this series, Russia is a bright red, that's how I see it. To someone with protanopia, as seen in the second image, it's more of a brownish-green. So I should be fine.

In this series, however:
what%20c3.jpg

I can clearly see the red dots in the first image, but can't make out the number.

So I probably perceive colors alright, but the problem, in my case, would be recognizing familiar shapes... maybe. :confused:

If any of us took a real Ishihara Test in an opthamologist's office, we'd be using a scientifically prepared test and get an accurate diagnosis for one type or another of color vision deficiency.

Using jpeg images on the web, with their various color spaces, presented through our particular displays, we're getting second-hard, informal tests. If you can't make out the shapes in the images I posted, it could be from poor color vision or simply from poor reproduction of the image. My wife says the shapes don't pop out instantly, but she can see them all.

noaccess, I can easily tell those color wheels apart too, so it's not a representation of my vision as a protanope.

In those four maps, I'd say Russia is either orange or green (I can't tell which) in the first three images, and red or brown in the 4th, with the lighter countries in the 4th image being either pink or gray.

I see no numbers in any of those circles of dots.

I can see the difference between the two images and make out that there are some shapes in the second but I couldn't really make out what they were. I got impatient though because I don't really "get" that particular kind of art, the kind you have to work for to see. Plus, after years of being prank startled on the web I kept expecting the little girl from the exorcist to pop out at me or something. I then checked that it was a JPEG and not a GIF. :p </traumatized>

I am not on the colo(u)r blindness "list", but I can see no numbers in any of the discs, although Russia is bright red in the first map, and many of my clients/customers rely on me for and value my colour advice... :)

I just read through this thread for the first time, and I found it very interesting!

I didn't notice anyone ask what I figure are pretty significant questions, though.

Does it bother you being color blind? Do you feel like you're missing out? When you ponder the spectrum of colors that you're able to see, is it even conceivable to you that there are entirely different colors every bit as different as between the different colors that you can see?


My experience tells me that most people don't like to be pitied, but I really think it would suck to be colorblind; it's sort of a "what you don't know can hurt you via deprivation" thing... You can't see green and purple, which are beautiful, but you're stuck with a whole bunch of ugly yellow.

Interesting image posted in post # 267, Dr. Q...

Fwiw, I see the following:

The numbers 52, 60 and 7 in bluegreen against the orange background (left).

An aeroplane in green above the number 60.

A tree on a hill, also in green below the number 52.

The numbers 1 and 4 in green to the left of the aeroplane.

A house just to the right of the orange field (in orange).

The numbers 4 and 18 in orange below the house.

A stick-figure man to the left of those numbers.

The number 6 in the extreme bottom left of the image, along with a line that I can't make out a meaning to...

A sun in the top right corner, the number 35 below and to the left, the number 5 below and to the left of 35...the number 1 right below 35...

A flower or a circle with a cross through it above the 5...a number 2 above that...a number 9 in the middle - far right (all of this in orange, btw)

In pink, I see the number 79 below the sun (and 9). I see either glasses or barbells below the 79 (just above and right of the 18). I see a 3 in a circle in the bottom right hand corner.

That's about it.

In the first image, the number is green, and the rest of the dots are red. If you don't see it, you can't perceive the color green.

Not in the least. My spectrum has no gaps.

None of those things is actually there. Does it bother you to know you are 20/20 delusional? :cool:

In the first image, the number is green, and the rest of the dots are red. If you don't see it, you can't perceive the color green.
Nonsense. It's not that black-and-white, if you'll pardon the expression.

I'm pretty sure I'm not colour blind and I found it hard to make out the shapes in the second one. I could tell they were there, and could make out a few of them, but overall I certainly wouldn't say they jumped out.

Those kind of bright colours are really hard to show accurately on a screen rather than in print, so it could be that the web image isn't quite right.

blackfox, you've confirmed that the stuff in the diagram is indeed in the original image, if your computer display and your eyesight give you the chance to see them. You should compare what you spotted with the diagram. What you called glasses or barbells is supposed to be a car.

I didn't realize that the digits in the diagram were actually part of the image; I thought the numbers in the diagram were a legend. Oops!

I didn't notice anyone ask what I figure are pretty significant questions, though.

Does it bother you being color blind? Do you feel like you're missing out? When you ponder the spectrum of colors that you're able to see, is it even conceivable to you that there are entirely different colors every bit as different as between the different colors that you can see?

I wish I could trade vision with someone else, just for a minute, so we'd actually experience what we understand only intellectually. My mom, with her normal vision, has the same wish, since she lived with a color blind father and then color blind sons. It was almost as if she was the odd man out in the family. But maybe I'd be better off without finding out first-hand what I'm missing.

I'm a bit jealous when people ooh and aah over a view that I know is 33% less colorful to me (sunsets are a common case of this), but it doesn't really bother me any more than it bothers all of us that we can't do a back flip on a balance beam, solve a Rubik's cube in 30 seconds, grace a magazine cover, stay in the sun without getting seriously sunburnt, graduate first in our Law School class, afford a big house, or use a computer mouse designed for only right-handed people. After all, some people can do those things. Compared to the social or physical problems caused by, say, autism or a cleft palate, color blindness is nothing to fret about.

Even though I know better, the answer is no, I can't quite conceive that it's so easy for most of you to distinguish colors, that pink and gray are instantly recognizable distinctly, that blue and purple aren't practically identical, and that rainbows really do have more than 2 or 3 colors. It still seems like magic when my wife admires a red-leafed tree in the fall while I see only boring brown leaves on a tree that doesn't stand out at all. But I know it's not magic at all. Once in a while somebody, knowing I'm color blind, will ask if I can tell two colors apart that are obviously different to me, and my first thought is "of course I can tell blue and yellow part... do you think I'm stupid or something?" But when that happens, I have to laugh at myself again, for thinking they should somehow be able to see things as I do just by hearing a scientific explanation.

We should all be jealous because we can't see infrared and ultraviolet!

Meaning what exactly?

I freely admit I can be prone to delusions - my relationships have had all too many of them...;)

I listed what I saw - due to color contrast.

As an aside from this (meaning back to the thread) - I have excellent night vision also, but find it hard to drive at night, due to my eyes constantly readjusting to bright headlight beams.

This is somewhat comparable to the fact that I have great hearing, unless there is a lot of ambient noise - in which I cannot hear anything clearly - even if the speaker is only a few feet away.

Really don't know what any of this means.

Aw, Q......today I was looking at a rainbow and I remembered our conversation about such. I admired all the colors I was seeing and thought, "but Dr Q would miss out on so much of this if he were standing here beside me looking at the same thing!"

Interesting thread! Just getting on the bandwagon

I just read through this thread for the first time, and I found it very interesting!

I didn't notice anyone ask what I figure are pretty significant questions, though.

Does it bother you being color blind? Do you feel like you're missing out? When you ponder the spectrum of colors that you're able to see, is it even conceivable to you that there are entirely different colors every bit as different as between the different colors that you can see?


My experience tells me that most people don't like to be pitied, but I really think it would suck to be colorblind; it's sort of a "what you don't know can hurt you via deprivation" thing... You can't see green and purple, which are beautiful, but you're stuck with a whole bunch of ugly yellow.

To answer your first question, in my opinion it doesn't bother me to be colorblind anymore than it bothers someone to not be colorblind. I really don't know the difference so I don't know what i'm missing! I've always wondered if I see colors that non-colorblind people don't see. I've got no idea what the answer to that is, but it's always intrigued me wonder.

I don't see it as deprived at all. To me it's normal. In fact if you think about it, probably the only thing that makes non-colorblind vision "normal" is the fact that the person that discovered the difference was not colorblind. Well, that and the percentages! It's all in how you "see" it, or look at it!

Now to add my own thoughts: I was 30 before I found out that peanut butter is not red. It had just not come up in conversation before. There was a radio commercial and a child was asking all these questions of his mom, one of them was "why is peanut butter brown?". I looked at my friend in the car and said something about that kid being screwed up! In return I got "that look", the one that's sort of half pity/half "huh"/and half laughing. OK, I guess those would be thirds, but you get the idea. Those of you who get that look know what I'm talking about.

I too have the problem with traffic lights, it's worse at night when you are in unfamiliar surroundings. Here's a new twist on that one though. In Hawaii, on the Big Island, all the street lights are yellow. HORRORS!! They are yellow to keep down the glare for the observatories on Mauna Kea. So it completely throws me off when driving there at night, I actually find myself driving a little more careful because of it.

I started off my adult life as a graphic designer. I made it most of the way through art school before a teacher discovered my secret. She pulled me aside and asked what color the wine bottle is. I knew immediately she was on to me. She suggested that I make a career out of painting the way I see life. Except that I hate to paint and the fact that I don't always get the colors wrong. If i see the usual brown grass (it's brown to me kiddies) I know that it's actually green. So If i'm mixing paints, I can grab the green or the brown and come up with the same color, at least to me. Then computers came along! I was all for it, dove right in and immersed myself into computer graphics. This was my downfall as a graphic artist. There is, to me, a significant difference in a color printed on a page and that same color displayed on a monitor. It's better on an LCD, but real different on a CRT. At that point I decided to switch fields and get into the computers themselves. I still do graphics on my laptop. Photos, I just don't mess with the colors. It's like messing with the color settings on the TV, I've been warned to stay away from that setting screen. Most other things, as stated earlier here, can be faked or just plain colored by the numbers. I don't really know if any other colorblind people have that problem (printed vs video) but I'd be anxious to hear.

You try to learn not to blurt things out in public if it's regarding a color that could be a problem, but you don't always know if it's a problem color or not. At a baseball game last week I asked a friend why all these older fans are wearing pink jerseys? They were all "huh?". I pointed one out, they told me they were grey jerseys, they were for the Rays Silver Fans or something like that. Another one of those oh well moments!

Actor Paul Newman, who died last Friday, joined the Naval Air Corps in the 1940s, wanting to be a pilot. But he was disqualified for the job because he was found to be color blind. He became a naval radioman and gunner instead, later turning to acting in the 1950s.

Wow!

Nice discussion going on here! I'm not color blind though it has been a very informative read - probably the best thread I've read in MR.

I only know one person who's partially color blind: can't tell blue from black, I think. We had a very verbally-charged fight on why I wasn't using enough colors for a Word document we were collaborating on. :p

I've always wished I was color blind for a day: try out what it feels like, etc. Closest thing to an experience like that was in MR-April Fool's Day. I woke up, turned on my Hackintosh, started Safari, cmd+5 (shortcut for MR), clicked one of the threads. After I properly cleared my eyes I was in a proper state of shock - everything was gray (and my "Mac" was using graphite)! Then I realized there was a big, red with gold "Kung Hei Fat Choi" banner behind my laptop. LOL!
