How Does Colorblindness Work?

Colorblindness is when your eyes can’t tell some colors apart, just like how you might not know if a sock is blue or green in a dark room.

Imagine your eyes have special helpers called cones that catch light and help you see color. Most people have three types of cones: one for red, one for green, and one for blue. But if someone has colorblindness, they might be missing one of those helpers, or it doesn’t work quite right.

Think of your eyes like a muffin tray that should have three kinds of muffins: red, green, and blue. If you're colorblind, maybe the green muffin is missing or broken, so when light hits your eye, it can’t tell if something is green or not, it might look more like red or blue instead.

It's like wearing a special pair of glasses that make some colors mix up. If you're colorblind, you might see a red apple and a green apple both as brown, or maybe they both look the same to you, just like how sometimes it’s hard to tell if your friend is wearing a blue shirt or a purple one from far away.

That's why some people need help telling colors apart, but it doesn’t mean they can't see them at all, just a little differently!
