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.
Figure 1: Rearranged Color Chips
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!
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…
