EDIT: found a cleaner version (pic8.co)
A computer only shows a limited number of shades so this test is limited to "normal" ranges of human perception.
You see less than 20 color nuances: you are a dichromats, which means you have 2 types of cones only. You are likely to wear black, beige, and blue. 25% of the population is dichromat.
You see between 20 and 32 color nuances: you are a trichromat, you have 3 types of cones (in the purple/blue, green and red area). You enjoy different colors as you can appreciate them. 50% of the population is trichromat.
You see between 33 and 39 colors: you are a tetrachromat, like bees, and have 4 types of cones (in the purple/blue, green, red plus yellow area). 25% of the population is tetrachromat.
