color blind (Score 1)

One thing I've had in mind for some time now is a kind of gimp plugin that simulates various kind of color blindness, so the user can get an idea of how colorblind people would perceive the images. Ideally this would enable designers to make their work more accessible to those people. Alas, I haven't yet found the time to learn enough about color science to build this.

Having this functionality in a web browser would to cool too and might encourage web designers to build accessible sites.
