Dichromacy

Dichromacy means that someone's eyes are not able to see all the colors in the world the same way as most people can. Imagine that colors are like different types of fruit. Just like some fruit might taste different to you than to your friend, some colors might look different to people with dichromacy than to people with normal eyes.

Most people have three types of cells in their eyes that help them see colors. These cells are like three different types of fruit sensors. They each sense a different color- red, green, or blue. When all three colors are mixed together, we are able to see all the amazing colors around us, like a rainbow or a beautiful flower.

However, some people with dichromacy only have two types of color cells in their eyes. This is like having only two types of fruit sensors that don't work well together. They might still be able to see some colors, but not as many as someone with three types of fruit sensors.

So, someone with dichromacy might see colors differently than other people. For example, they might have trouble telling the difference between red and green. This can make things like traffic lights or stop signs confusing for them. But, just like some people might prefer one fruit over another, some people with dichromacy might even have special abilities, like being able to see different shades of certain colors better than other people can!
