When I was in first grade, I took a strange test in which I had to identify numbers hidden in a field of small circles.
There are a few video games that I'm unable to play because they require quick sorting of colors that I have difficulty differentiating.

Tripathi is developing an extension to Google Chrome, called Re Color, that would let color blind users adjust colors using settings of their choice.
