Well I certainly couldn't see the three, and I'm always confusing greens and browns, but I guess my colour blindness must be mild. I thought it looked like the axis was at a right angle to what it should be. :confused: Maybe I just can't see it...

Couldn't see the three what?

The axis is the same for everyone...the tritan-axis illustrates where you would have screwed up if you had problems with your "blue" receptors. But you did just fine there, and everywhere else...your profile doesn't show any lines crossing the center of the ellipse.

So, Q, what does my avatar look like?
Here is your avatar before and after processing by a color blindness simulator. They look just about the same to me, so I can't tell if the filter did much to the image. If they look different to you, then the right-hand one shows you what I see.

*tries to make Doctor Q mad* :mad: :mad: :mad: :mad:
Conveniently, I'm already as mad as a hatter.

For me, picking out a tie to match a dress shirt is almost impossible. I don't wear ties often, but I've always brought along somebody color sighted when I needed to buy one.

If you have bought one, what about writing the color on the back of the tie with indelible ink ? If you do the same with your colored shirts, wouldn't that help to put together a 'correct' ensemble ?

Sometimes I wonder if my son is colorblind. He is 4 years old and confuses the colors blue and green ? Does anyone know if this is just his age or something more that I should keep an eye out for ?

The one on the right is olive drab, whereas the one on the left is bright red. Interesting. (good thing you were a deposed czar, as being a red commie could've been difficult ;) )

So the little red angry faces dont affect you?



Thanks again for answering my questions. :)

A friend at work is hardcore red-green blind .. a great tool for testing accessibility.
And a bunch of other friends have some issues with some green/blue tones...

Are there any limitations for the extremely colorblind for donating eyes? When the retina would be used .. would the person who would receive the eye, also be colorblind?

I was reading my biology book a little while back month or two and they had a test circle with a seven in it supposedly.

I'm like Q, I have protanopia. (psst. Q. hardly any of the photos look different.)

It really strange, I'm an artist paint and photoshop a lot. I get by with photoshop by the RGB values and In art class I would always ask "would pass the red/green paint to me?" and take others opinions.

If the reds or greens are bright enough like lime green against bright red I can tell which is which, but knock down the contrast and They very rapidly blend together.

<Thanks Q>
This is one if the best collections of information I have found and a lot of easy ways to explain to people how see the world differently.

I HATE color coded maps. They like to use colors like red and green becuase they stand out, of course the colors that give me trouble.

Texas, unfortunately.
I'm VERY slightly color blind.

I can tell the difference between the Wizard of Oz pictures, but I don't see a 3 in the first post.

It doesn't affect me too much, as color has little if anything to do with my life. (well, except for my posts on MR :))

Here's something I deserve to be teased about mercilessly.

When I was a kid, my mother told me that to do laundry the first thing you do is sort the clothes by color. She never asked me to help with that chore, and that made perfect sense to me, since how could I possibly sort clothes by their colors? Red, brown, green... I'd never get them right.

It was years before I learned the real truth... that sorting by colors really means separating white, light, and dark clothes, with some special categories like permanent press, towels, or delicates. You don't have to be able to tell blue from purple to do laundry!

I felt stupid for "not being able" to do laundry for so many years. Then I felt stupid for not helping for so many years. And now I'll feel stupid for years for telling you this embarrassing story!

To atone for my evil past, I've insisted on doing all of the family laundry at our house for years (in exchange for other chores). Best of all, that gives me a chance to use my secret shirt-folding technique!

So here's a tip for color blind kids: tell mom and dad that you can't help with the laundry because of your disability, and you might get out of a chore! ;)

1) First of all we're all almost completely color blind, so I don't feel that sorry for those who are a little more color blind than others. I doubt very many of us lay awake at night lamenting that we can't see into the ultraviolet spectrum. From a physics point of view it's really ridiculous to think that any of us are seeing the 'true' colors. OK, so it makes it a little harder to play video games and look at some art. Still- we're all lucky enough, smart enough (and rich enough) to own Macs, so life can't be that bad!

You were nearly there, its not that we are nearly all colour blind, its that technically as a species we are just blind because of the portion of the electromagnetic spectrum we can't see.

On another note, my photography lecturer is colour blind but makes amazing judgments when it comes to assessing photographs. He must be able to determine the errors in a photo by knowing his hues.

Also I've done a lot of research into colour theory and I once a few years back started to make art as colour blind people would see them. That way people who could see the entire visible spectrum were not at an advantage when looking at the piece of work.

This thread has tempted me to start me off again. I'm not colour blind either.

My mom has always said that she'd love to be able to see the world through my eyes for a day.

I wonder if, one of these days, I'm going to wake up in a bathtub full of ice with my retinas missing! :eek:

If so, I'll know who to suspect. I'll just have to figure out how to dial 9-1-1 and have the authorities retrieve the stolen property from her.

It may sound corny, but the fact that I can see is the most important thing to me. I can't imagine what it would be like to not be able to.

I agree. I dont really give a monkeys that I mistake green trousers for brown I can see. its more important for me since I am completely deaf in one ear and partially deaf in the other. I dont analyse what I aint got just thankful for what I do have. Hey I love the fancy labels for this condition, got any for me...apart from cloth ears

Wow. I really never realized what it looked like to be any of these types of color-blind. I have a long-distance friend who indicated his color-blindedness, and while I don't know the type or severity, I was afraid to ask as if it were something embarrassing. It shouldn't be, I now know, thanks to all of the brave and informative posters in this forum. Actually, I do some photo-editing and graphic/print design and I had never considered color-blind individuals in my design, nor did I know that there were online websites and tools to simulate this for assistance. That is so cool--I'll never not think about the colorblind again.

It's ironic that I'm a big fan of the musical Wicked (I saw it for the second time last week) even though one of its attention-getters is that the lead character (Elphaba the witch) has green skin in the show. At least that's what I'm told.

I assume that Julia Murney is green in this publicity photo, but I can't tell. Other than being so stylishly dressed ;) she looks like everyone else to me.

Really? I'm surprised. But I guess I made my point - I don't know the difference.

How 'bout the flesh color in this photo (also Julia Murney) or this photo?

green alright. well, the witch anyway :D

I've always wondered about being colourblind, a friend of mine from highschool couldn't see green, I remember asking him lots of questions about that. Thanks for starting a very interesting thread.

I've always been curious, and forgive me if this has already been asked, but is there a form of color blindness where you don't see any color at all? Just all black and white?

Well, she looks green to me, though it's a very light green. Except for the pinky on her right hand -- it's normal skin color. The makeup must have rubbed off. ;)
