Are You A Tetrachromat?


Look at the three circles above. If all you see are three circles filled with dots of the same color, you are normal. If you see something different (such as different colored letters inside each circle) you may be a tetrachromat: very rare and super human.

A tetrachromat is sort of like being a super taster of color vision. To date, only two or three people have been identified as potential tetrachromats. You might be one.

It cannot work whit 3 chromatic monitor and JPEG compression... This test is a fake!

Actually, a recent study has found that 50% of women and 8% of men have been found to possess anomalous tetrachromatic vision. But the previous anonymous poster is correct, jpeg artifacting along with standard 24-bit monitors would render even a legitimate web-based test ineffectual, much less this fake one.

I just added the 4th channel with photoshop, and increased the contrast and nothing changed in regards to the structure. This test is impossible on monitors tailored to that of trichromats.

No letters inside.... just three purple circles of dots

Only being able to see three or four colors must be really weird and dreary.

The middle orange circle has an italicized Times New Roman “T” mostly on the bottom right.
