Not exactly what you were asking, but you can check your software/webpage/publications with a tool like Color Oracle. It simulates different types of color blindness on your computer screen.
I remember using it for a university project in 2007, in which we had to build a movie lookup website from scratch. I used Sim Daltonism to design 3 alternative CSS that would cater to the needs of people with different types of colorblindness (there's not just one type, although deuteranomaly (red/green colorblindness) is the most widespread).
The teacher thought it was superfluous and took points off. sigh :)
It's amazing how something so seemingly minor can make such a huge difference. I feel like I'm traversing the web of yesteryear (true yesteryear, not the animated gif'd web of 1997). Thanks for the link OP! One critique: The desaturation occurs a noticeable ~300ms after the page starts displaying, which means I always get a brief flash of colour.
apart from that flash of color, I am really enjoying it also.
It is almost calming, and allows me to focus on content much more easily - very similarly to the way readability or instapaper do without the need to switch contexts.
It actually forces something even more fundamental. In the HSV colorspace, a black and white image has no hue or saturation, only value. Since value is the main contributor to contrast it is the color dimension that contributes most to usability, comprehension and attention.
Thanks -
this strangely makes using the computer a more soothing experience. Tried it for a few minutes, when I turned the color back on, it seemed suddenly very loud.
It is not a dumb question, but the answer is almost certainly not.
It wouldn't be that difficult to design a computer to process graphics a lot faster in greyscale (you need to use one byte for the color and one for the alpha) since each pixel requires less computation.
In practice if your graphic card only worked in greyscale, it wouldn't be worth the cost of development and so nobody would do it.
The equivalent under Linux is available in Compiz Configuration Settings Manager (ccsm), listed as "Color filter". It includes grayscale, several forms of color blindness as well as some novelty effects.
On firefox, the original HBR article, when viewed with this plugin completely wipes out the page. You may want to check your plugin on that page to see why it messes up your code. :)
Combine this with F.lux, which adapts your display according to the time of day (at night you'll find your monitor quite pleasant to look at). http://stereopsis.com/flux/
>I imagine there would be no perceptible difference when dealing in greyscale.
Not so: changing the color temperature changes how white looks.
It's night, so F.lux has lowered the temperature of my Mac, and if I hold my iPad up in front of my Mac's display white on the Mac look distinctly red-tinged compared to white on the iPad.
Damn, you're right. I also just tested it (a better test is to hit the "24 hour preview", though I must warn you it is overwhelming).
I was figuring it would only change the hue, but in retrospect that doesn't make any sense. It wouldn't do a lot of good since a great deal of websites/apps use white heavily.
It allows not just grayscale viewing, but colourblindness of different forms, and other visual impairement. Really fascinating. Runs for your whole computer, so you can test apps and other stuff too.

This forces people to test and comment on the functionality rather than simple aesthetics.

Display: [x] Use grayscale
This might be the dumbest question but is there a system performance benefit in using grayscale?

Google's official high contrast accessibility plugin has a greyscale option, and no flicker on page load.

Thanks for pointing that out.
I'll be reading it with the plugin deactivated ;)
