ABC Zoom, Colour vision: cone cells work by helping us see all the different colours around us, like how a rainbow has lots of shades.
Imagine your eyes are like a big box of crayons. Inside your eye, there are special helpers called cone cells, and each one is good at seeing a certain colour, red, green, or blue. When light comes into your eye, these cone cells jump in to say, “I can see that!”
How the colours mix
Why we can see so many colours
Your eye has lots of these cone cells working side by side. Together, they send messages to your brain, which puts all the different colours together, and that’s how you can see a whole world full of bright, fun pictures!

How the colours mix
If only one cone cell is working, you might just see a basic colour, like when you use only one crayon. But when all three kinds of cone cells work together, red, green, and blue, they make new colours, like yellow or purple, by mixing their signals, just like how you mix paints to get new shades.
