![The color nuances we see depend on the number and distribution of cones in our eye. You can check the image of the rainbow photo above. How many colors do you count? [698x400 - 20KB]](https://pic8.co/sh/JJki6b.jpg){kind=link}
That explains why I see gradients within each color stripe.

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.
