This links to a website about color blindness or, more correctly, color deficiency. It was created by Frank Dutton, a web designer in Louisiana. Briefly, it describes the condition, causes, and effects of color deficiency. The primary purpose, however, is to furnish a set of color charts to aid the color blind in working with computer colors, most especially on the internet and in web sites. There is also some really nice software (shareware/freeware) here for checking colors onscreen on your computer - great for anyone, but especially for the colorblind! An example of a test chart for color deficiency is shown to the right. The individual with normal color vision will see a square and circle revealed in the dot pattern. An individual with Red/Green (the most common) color blindness will see only the circle revealed in the dots. -- Dr E
