What is trichromacy?

Trichromacy is when you can see three main colors, red, green, and blue, and mix them to make all the other colors you see every day.

Imagine you have a box of crayons with just three colors: red, green, and blue. If you mix red and green, you get yellow; if you mix green and blue, you get cyan; and if you mix red and blue, you get purple. When you put all three together, red, green, and blue, they make white.

Your eyes have special sensors called cones, which are like tiny color detectors. You have three kinds of cones, one that detects red, one for green, and one for blue. When light hits these cones, they send messages to your brain, and your brain mixes the colors together to make everything you see.

Most people have trichromacy, which means they can enjoy a full range of colors in pictures, food, and even toys. If someone only has two types of cones, like some animals do, they might not see as many different shades, kind of like having only two crayons instead of three!
