Only 25% of People See All Colors

What is perfect red? Which yellow is ‘canary yellow’ and which one is ‘mustard yellow’? Is there any real difference or those are just fancy names for the same color yellow? How about ‘blue’ and ‘powder blue’? When we see and talk about color how do we know that the person we’re trying to communicate our vision sees the same specter of  color palette?

Here is a little test from Professor Diana Derval, an expert in Neuromarketing. The color nuances we see depend on the number and distribution of cones (=color receptors) in our eye.

You can check this rainbow: how many color nuances do you count?


If you see less than 20 color nuances: you are a dichromats, like dogs, which means you have 2 types of cones only. You are likely to wear black, beige, and blue. 25% of the population is dichromat.

If 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.

If 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). You are irritated by yellow, so this color will be nowhere to be found in your wardrobe. 25% of the population is tetrachromat.

You see more than 39 color nuances: come on, you are making up things! there are only 39 different colors in the test and probably only 35 are properly translated by your computer screen anyway.


P.S. I counted exactly 39 colors; however, I very much like yellow, ‘canary yellow’, to be precise. 🙂
