Here's a cool link that Echo shared with me.
It's called the Online Color Challenge, and it ascertains how well you see color -- and how well you can differentiate between the various hues of a color as they evolve from one value to another. In its orginal form, this contains four rows of jumbled-up color chips that you need to drag and place so that each color chip is suitably similar to the ones before and after them.
I am going to show you how I managed to rearrange all the color chips -- even though I did not get it entirely right! Figure 1 shows my rearranged clips. And you can click this and other figures in this blog post to see larger previews.

OK -- Figure 2 is how my results look like -- my score was 12 -- and smaller scores are better than larger ones. One of my friends got 3, and someone else was somewhere near 90!
Figure 2: The score
I was then asked to provide my age and gender, and my score was compared with others who were the same gender in a similar age group -- and this comparison was shown in Figure 3.

This is great fun if you have 10 to 15 minutes to spare -- go here to play...

Color blindness is some sort of color vision deficiency which results in differences in the way that an affected person sees and distinguishes various colors. It is mostly inherited, but can also be caused due to damage in the eye, nerve, or brain. There is no proven way to change these vision deficiencies.
When a color blind user looks at a PowerPoint slide, he or she might view it differently than other people. Even different color blind users may not see the same slide with the same vision -- there are three known varieties of color blind visions.
