It’s become clear that people’s capacity to discern different colors differs significantly. The reason for this is because each of us has a different amount of cone cells inside our eyes. These cells are photoreceptors, and the quantity of them determines how many colors of the visible light spectrum you can distinguish.
Professor Diana Derval devised the short exam presented below. You may discover out how well you perceive the world around you – and how much your perception differs from other people – by answering the question and then checking the results.
Count the number of colors and hues in the spectrum that you can see:
You’re a dichromat if you see… less than 20 colors. This indicates you only have two kinds of cone cells. Professor Derval quips, ‘However, don’t worry – you’re in excellent company here, because dogs have exactly the same sort of vision as you.’ Perhaps your favorite colors to wear are black, beige, and dark blue. Dichromats account for 25% of the world’s population.
Colors ranging from 20 to 33: Your eyesight is trichromatic. This indicates that there are three different types of cone cells in your eyes. Purple, dark blue, green, and red colors are well-perceived by you. This is fantastic; half of the world’s population shares your perspective.
Colors in the range of 34 to 39: Wow! Tetrachromatic vision is what you have. You have four distinct types of cone cells in your eyes, similar to bees, and can perceive the majority of colors in the visible light spectrum. You’re probably not a lover of yellow and have very little yellow clothes in your closet. Only 25% of people can see the entire range of colors.
It’s always fun to compare your results to those of your friends. Maybe you’ve known a tetrachromatic individual your whole life and never realized how unique they are!
