How does the human eye perceive different colors?

The human eye sees different colors because special parts inside it catch and mix light in clever ways.

Your eyes have little helpers called cones, and they're like tiny color sensors. Just like how your skin can feel hot or cold, these cones help you tell red from blue or green from yellow.

Imagine you have three friends who each love a different kind of candy, one loves chocolate, another loves gummy bears, and the third loves lollipops. Each friend tells you what kind of candy they see, and together, you figure out what’s in the bag!

Your eye works like that:

• Red cones react to red things.
• Green cones react to green things.
• Blue cones react to blue things.

When light hits your eye, these cone friends send messages to your brain. The brain mixes them up, just like mixing paint, and you see all the beautiful colors around you!

At night, when there's not much light, your eyes use other sensors called rods. Rods are more like night vision cameras, they help you see shapes and movement, but not the pretty colors. That’s why things look gray or black in the dark!
