Vischeck has come up with an algorithm to 'Daltonize' images, that is, shift the colors and contrast in a digitalk image so that the differences between objects are more visible to color blind users. The algorithm can adjust for different types of colorblindness.

Possible applications include: digital microscopes, digital video recorders, computer displays, and print media (especially where legibility is particularly important--maps, public safety documents, etc.)

Vischeck also allows you to check any web page to see how it looks to anyone with specific kinds of color blindness.
