In the image above, count how many colors you see. LISTEN THERE IS NO RIGHT ANSWER. If you see lines on the same color, count it as 1. DON'T ZOOM IN! Just click on it and count really really fast, as fast as you can. Then scroll down AFTER you've done that.

If you see 20-32 colours, you are a trichromat! You have three cones in your eyes (one for purple/blue, one for green, and one for red). You are the majority of the population.

If you see 33 or more colors based on a quick count without zooming in or adding on anything at all, you are a tertochromat! You have 4 cones in your eyes like bees! The extra cone is for yellow, and that color irritates you (I am a tertochromat at it does a LOT)! Congrats, this is an uncommon skill!

Comment what you are, don't feel badly if you are a trichromat most people are! ;)
