i spent a few hours looking at info on tetrachromacy, and some sources say it can only occur in women, some say it's possible in men. Try this test
X-Rite: Get exactly the color you need, every time, anywhere in the world.
I had one tile off, and I realized it just as I clicked to end the test. What bothers me is that there seems to be a shade of color missing toward the left of the third row, while the other three bars seem alright.
