This is crazy!
Did you know that about 75 percent of people can't actually see all the colors? I'm among them. My dad figured out that I'm colorblind when I was a young man. It's pretty common apparently.

How you see colors comes down to how many cones you have in your eyes. Your cones are basically what receive colors. This simple test can tell you how well you see colors. Simply count the colors you see in the spectrum above.
How many colors did you count?
If you saw fewer than 20, you're a dichromat.
If you saw 20 to 32 colors, you're a trichromat.
If you saw 32 to 39 colors, you're a tetrachromat.
You have four types of cones in your eyes. You may find yellow to be a rather irritating color and don't ever wear it. 25 percent of the population is a tetrachromat.
If you saw more than 39 colors, count again.
There are only 39 different colors in the test. You're probably a tetrachromat, though.
