First off, I don't think you're colorblind. I also think you shouldn't judge color or conduct any color test on an uncalibrated monitor and especially on a low quality display like the KDS. I tried out KDS monitors at Walmart and they don't look to good even when calibrated. They were overly bright and washed out looking even after calibration.

Secondly, I don't know what you were trying to test for on those RGB purity bars. They both look the same as they should be because the eye can't distinguish between 255 to 253 in intensely saturated colors as you posted. It's physically impossible due to the way glaring white light next to electronically charged phosphors at their peak bombard the eye like automobile headlights at night.

I have the same red/green/yellow/orange shift problem with fleshtones as well, but that's normal and it's very subtle. Even the best prepress pros and digital imaging specialists go by the numbers as a standby to double check the color especially for fleshtones.

Color temperature of your monitor against your ambient light color cast has a significant affect on fleshtone color perception among other colors like pastels. Both should be as close as possible to each other in color cast. The red/green shift you described is referred to as adaptation and it's always best to look away after awhile when editing color on a display for these very reasons. Also the amount of coffee you've consumed has an affect on subtle color perception as well.

Go to the top ICC Frontier post with my name as the last poster and scroll down to where I've linked a restoration project showing color shifts printing to a Noritsu and tell me if you can see a difference between the top right baby and the bottom right. If you can't, check the numbers in the each file. There is a significant increase in the red channel on the bottom one by at least 10-20 levels in some colors. If you can't see it, then you have a calibration problem, not colorblindness.

But it can't hurt to check with your eye doctor to make sure, anyway.

This thread worried me, so I did a colorblindtest:
I past very easily, so I was very glad I wasn't colorblind!
But then I also did the test from Doug's link:
and again I past!
I am confused

But honestly, I think you have a serious problem when you are colorblind in the graphics industry!
I am not an expert, but I hope that there is a cure or something! Maybe you can train your eyes to overcome it!

HI Adam!
I'm a color blind too.. I find that out when I was 18 years old, on the army recruitment test.
Anyway Before that test and after that, I may say that for almost 12 years I work as a designer. I often have problems with the colors, but I always keep some trusted person close to me to correct my colors...

My advice is: if you want to keep your job don't tell any one about this, just play along... And when things get critical then just give an excuse that your eyes are tired . It works for me... Another thing is that you can always correct the color of the monitor to increase the colors that are your weekness (green in my case...

One other thing, start learning the html codes and color mix percentage for some of the color that you are blind to, that way you can always know what color are you working with...

Let me know if you need any advice..

I remember something that I saw many years ago on Beyond 2000 about electroshock stimulus for colorblindness (this episode was done in Japan). The effect will only last for a few weeks or months before the colorblindness comes back, but at least during that timeframe, those who had the therapy could distinguish the different colors. I personally wouldn't put shock pads on the temples of my face and go through this regime, but I'm not colorblind either, so I can not think like someone who is. I just tried to Yahoo (I don't Google) this, but could not find it. Oh well. I guess it was deemed too dangerous to be viable anyway.
