It is hard.

If I adjust my TN laptop screen angle just right, there is one green square that looks a little brighter than the others. But it is very subtle to these eyes. I don't think having-a-word-for-it is key. When I was in college, one day in the library another student asked me if I could pick out the numbers in the famous pictures of dots of various colors. It was relatively easy for me - but he couldn't see some of them. Not having a word for blue or green wasn't his problem, it was his genes. Cheers, Scott.

My MacMini is attached to an HP 24" IPS screen with a larger-than-usual color gamut and a fluorescent backlight. My Bulldozer PC is attached to a 24" Dell IPS with a conventional gamut and LED backlight. Both of the circles of green squares look very similar and I can't pick out the different one easily. (Both were running the Chrome browser, if that matters.) Apparently there is no tetrachromism in these eyes. :-) Cheers, Scott.
