Interesting test. I got a 4, much better than I expected, on my RMBP.

Anyone else here take the XKCD color survey back in 2010: http://blog.xkcd.com/2010/05/03/color-survey-results/

I was presented with an awful lot of colors I didn't have a better word for than "tan", "beige", "green", etc, so I expected that my "color acuity score" would be poor.

Looks like I was having trouble without something to compare to, and having trouble naming, rather than having trouble identifying differences between shares. Good to know!
