that claim is quite dubious. I don't think it's possible to create metamers for people with normal 3-color vision on an RGB monitor. To do that you need an extr

  Hmm... I'm not sure about that. It's an interesting question. It's equivalent to the question: can we create two images on a computer monitor that appear the same to a person with normal color vision yet appear different to a colorblind person? I think it would depend on the particular mapping from 3 to 2 dimensions... it might be possible.

It surely depends on the type of colorblindness, there are many [1]. [1] http://en.wikipedia.org/wiki/Color_blindness http://en.wikipedia.org/wiki/Color_blindness If you're monochromate or dichromate, I doubt that this is possible. Monochromates or dichromates are simply missing one or two color components out of three. If you have anomalous trichromacy, you can by creating a monitor with pixels of different colors. In any case, I don't see how it is possible to identify a tetrachromate with a trichromate (RGB) monitor. I tried to increase the contrast and change the hue of the color test to understand what was different between the apparently similar colors but I wasn't able to find any difference.
