What is dichromacy?

Imagine you have only two colors in your world, everything else looks the same to you. That’s what it’s like being dichromatic, or having dichromacy.

You know how sometimes when you look at a rainbow, there are seven different colors? Well, if you had only two of them, say red and green, then blue would look like green, and yellow might look like red. It's like wearing sunglasses that change how things look, not magic, just a special kind of color filter in your eyes.

Your eyes have tiny color sensors called cones, and normally you have three types of them, one for red, one for green, and one for blue. But if someone has dichromacy, they only have two kinds of cones working together. That means some colors mix up in their brain, making it harder to tell certain shades apart.

Imagine you’re playing with blocks, all the red ones look the same, and all the green ones look the same too. If there's a blue block, it might feel like it’s one of the green ones. It’s not confusing, just different, like having a special way to see the world! Imagine you have only two colors in your world, everything else looks the same to you.
