Here's a challenge for you: Try to imagine a new color. One that you've never seen before. Just straight invent one. Can't do it, right? You probably figure it's because you've already seen all the colors that are possible. Well, prepare to have your mind blown -- there are lots of new colors out there, we just don't ordinarily have the ability to see them, so describing them to you would be like trying to describe sight to a blind person. And we say you can't ordinarily see them, because science has figured out a way.
In their incessant quest to break reality in ever more interesting ways, scientists successfully managed to show some people a "bluish yellow" color. We don't mean green. We can't really show you what we mean, because the way our eyes work is that when we see blue, the parts of the eye that detect yellow switch off, and vice versa. So it's not supposed to be possible to see a true mix of blue and yellow. Green is something else, the closest thing your brain can offer when you show it something that gets it all confused.
But scientists discovered that we can sense these and other colors that don't show up in the rainbow by fooling our eyes with certain composite patterns. For instance, when you see an image like this ... ... and cross your eyes like it's a Magic Eye puzzle, some people can see an entirely new color that is neither blue, nor yellow, nor green. Then again, some people just see a gradient blob of yellow and blue and assume they're the victims of some prank.
If you think we're just messing with you, there's an example of one such impossible color that most people can perceive without playing complicated tricks on their brain. We call it pink. Pink is an unholy mixture of red and violet that doesn't appear on the rainbow any more than bluish yellow does. Seeing pink is basically the color equivalent of seeing ghosts.
And then, most amazingly, there are the very rare people who are born with the ability to see this world of new colors that the rest of us can't even imagine. These people are called tetrachromats, because they have four cones in their eyes instead of three like the rest of us. Each cone is responsible for seeing about 100 shades, so for us normal folk, that's about a million colors. But for tetrachromats? They see a hundred million colors. We should be thankful that it's rare, since it would make art class harder than AP history.http://www.cracked.com/article_19986_th ... ng-it.html
