What is color? - Colm Kelleher?

Color is what makes things look different under the sun, like how your red shirt looks bright next to your blue pants.

Imagine you have a box full of crayons. Each crayon has its own color, red, blue, yellow, and more. Now think about light. Light is like invisible paint that comes from the sun or a lamp. When it hits something, like your crayon drawing, some parts of the light bounce back to your eyes.

If you draw with red crayon, most of the red light bounces back, that’s why you see red. If you use blue crayon, most of the blue light bounces back, that’s why you see blue.

Now imagine you have a rainbow. A rainbow is like a super-smart crayon box with all the colors in it, red, orange, yellow, green, blue, indigo, and violet. Each color has its own special place in the spectrum of light, just like each crayon has its own spot in your box.

So when you look at something colorful, it’s because different parts of light are bouncing back to meet your eyes, just like how different crayons make a picture come alive! Color is what makes things look different under the sun, like how your red shirt looks bright next to your blue pants.
