Huh, I checked out the RGB values in the linked Boingboing post[0] too, and didn't notice that one had green 187. I very much doubt that was intentional or what they were testing for. Interesting that you found the larger difference to be easy to spot--I saw the difference but only after looking carefully. What I found most fascinating was the screenshot in the Boingboing post of the person looking at green squares with one aqua. I suppose they could have a very high incidence of tritanopia, blue light insensitivity, and in fact the spectrum shown here[1] matches up rather nicely with what's in the screenshot. I'd be surprised if this wasn't taken into account, though.
