How well do you see color?
http://www.xrite.com/custom_page.aspx?PageID=77I got a score of 8 in a first try. Not too bad, but not perfect.

4 on first try!
And I thought men had only 4 bits for color.
I'm leaving my job and starting a career in interior decoration.

Only 27 the first try. Then I got a perfect score the second time!

Lol. Maybe we only miss a checksum unit...
But it really DOES depend on X chromosomes:

Now, umm... hey friend, you know that... how should I say... that you've selected green as your head color?
- Technical note: Show Spoiler
If someone can't reach a score of 0, it could be caused by a de-adjusted monitor as well. And I don't mean "uncalibrated" here; especially calibrated monitors *could* cause a reduction of color space. This depends on the method used for calibration. For example, if the color correction is done in the color palette on the graphics card, or inside the monitor itself, when the monitor uses only 8 bits for controlling the pixel brightness, this could result in a level decrease from 8 bits to 7 or 6. In that case, colors ramps would lose their smoothness. For that reason, newer monitors (not the cheap ones) use 10, 12 or more bits per color to control the pixel brightness.

184 - no surprise there.
I've tried, on a couple occasions in the past, to create a personal colour correction profile, which might compensate a little, but never had much success.
Maybe these results may help, next time I decide to have a go at it...
Problem is; I don't think it's only a matter of photoreceptor response curves, which would be easy to remap; but just as much one of how the brain processes the data, with a whole host of factors affecting impression, not least of all being fill areas and local and global surrounding image balance.
After all: A monitor really only have three wavelengths and colour blindness test cards still works, when displayed on them...
On that bar chart: Does anybody else see (other than my usual colour-blindness-induced sudden shifts in hue along the spectrum, between areas with little change; which you won't see) individual scattered columns, that appear to have drastically lower value than their neighbours?
