1 in 12 people have some sort of color deficiency. When you're designing for the web, this means that 1 in 12 people might not be able to see your site. That's alot of people. This tool helps you simulate the appearance of our site's colors for people with different color visions. Select text and background colors from the palette below, then choose a color vision mode.

Not sure if you're color blind? Try an online Ishara Plate Test to find out. If you think you might be, I would suggest getting a real test, since color reproduction on computer screens varies wildly!
