No word for blue

And without a word for the color, there's evidence that they may not have seen it at all. Regards, -scott Welcome to Rivendell, Mr. Anderson.

She has a series set on an alien world where the natives are almost human in a lot of ways - but not at all in one very interesting one: they cannot see red. It becomes a crucial plot point because the POV character is a human of earth who can see red. :-) Wade. Just Add Story http://justaddstory.wordpress.com/

Being a throwback camouflage doesnt work on me. Often while driving I will point out wildlife that is quite plain to see, but no one else in the car can.

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.

Post #399,622 by Another Scott 3/1/15 9:02:10 AM Reply	I tried it with a couple of other LCD monitors. 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.

Post #399,626 by malraux 3/1/15 11:38:53 AM Reply	I managed to spot it Or at least, I thought "huh, I wonder if it's that one". It was very subtle, however, and surprising to me because my color vision is somewhat screwed up from all of my eye issues. Regards, -scott Welcome to Rivendell, Mr. Anderson.
