Understanding Absorption of Light - Why do we see different colors?

We see different colors because light behaves differently when it meets objects, and our eyes catch these differences like a detective catching clues.

Imagine you have a box full of rainbow-colored marbles, red, blue, green, yellow. Each marble represents a kind of light. When sunlight shines on something, it's like all the marbles are rolling out to say hello. But if the object is red, it’s like only the red marbles stay; they're the ones that absorb (take in) the other colors and reflect (send back) the red one.

That’s why we see a red apple, because it reflects red light and absorbs most of the others. A blue shirt is blue because it sends back blue marbles and keeps the rest. Your eyes then take those reflected marbles and turn them into colors you can see!

How Our Eyes Play the Game

Your eyes are like tiny detectives that catch the reflected light. When red marbles come bouncing back, your brain says “red!” when green ones arrive, it says “green!”

So next time you look at a rainbow or pick an apple from a tree, remember, it’s all about which colors get to play and which are absorbed!

Examples

  1. A red apple appears red because it absorbs all colors except red, which is reflected back to our eyes.
  2. Why do leaves look green? Because they absorb most light but reflect green wavelengths.
  3. A black shirt feels hotter in the sun than a white one because it absorbs more light.
