So...I\'m red-green deficient somewhere...never been properly diagnosed, but it\'s intrigued me for years. A friend of mine and I were having a conversation the other day that provoked me to look up color deficiency simulations, and came across some interesting things(I guess...it\'s all weird and conceptual for me, mostly)

The first page(tinyurl\'d because TGC doesn\'t like %20\'s iirc): http://tinyurl.com/3mnmt

Quoting myself from facebook(pinpointing *all* of the differences I see):
Quote: "Going through the list though, on the maps, the Protanope is no different than normal, on Deuteranope only China is really different...Tritanope is pretty [messed] up though. I don\'t get any of the dot tests, they all look the same to me? On the balloons, there\'s a very minor difference in red and yellow areas of the Protanope, but it took me a couple minutes to see them. About the same for the Deuteranope except that it\'s slightly easier to see the difference. On the stop lights, only the red is different, and that took me a few minutes to see on my computer. The shrub with the berries, the berries are relatively easy to tell the difference, but only after it got pointed out to me that the berries on the right were green. On my computer, the chick in the green dress is blaringly obviously not red. Those are all the differences I see in all of the images."


On this page, there are no differences in any of the images, whatsoever to me: http://mattwilcox.net/archive/entry/id/513/

This is a really interesting quote from that page that peaks my curiosity(it blows my mind equally):
Quote: "Trying to imagine that red and green are in fact as contrasting as blue and green blows my mind - I can’t visualise it."


Then there\'s this image...it all looks the same to me color to color, although after a little while I noticed that dark red under protanope is darker than the other two:


Any comments folks have are welcome...this is all very interesting to me. I wish I could see rather than just try to conceptualize the differences...

could be your monitor? I see a distinct difference in each color, but my color vision was rated perfect by the army.

Nah...I've been partly colorblind since birth. The worst for me has and probably always will be purple...it's simply not a color. It's always either blue or pink. My monitor is also pretty vibrant...in the first link, when I was looking at it on my sisters computer, I really couldn't tell ANY of the differences(although everyone else in the room could), and while I pick up on more of the differences with my computer, my experience is nowhere near what everyone around me seems to describe.

Back in elementary school I almost failed an art class for coloring my sky purple, it took bringing my mom to the school to confirm my problems with color to get past that

Why would you fail art for drawing the sky purple? Isn't that included under the well known "Artistic License?"

We were supposed to be drawing a realistic picture, and my art teacher was convinced I was just trying to cause trouble in her class. She wasn't a very good teacher.

I've seen purple skies before, so it's completely realistic!

The sky looks purple after you've been looking at a pool.

If you swap the red and blue channels in the image you should be able to see how different red looks from green to us. (Except that red is about twice as different from green as blue is, at least to me anyway...)

This is a very strange concept to me. I've heard that red and green next to each other can create the same faux 3D effect that red and blue next to each other do. And with what you said about swapping the channels, that would essentially be the same as comparing blue to green from my perspective, no? As for that, they are about on the same par as the red/blue contrast minus the possible faux 3d effect.

I tend to confuse myself when I talk about colors...
