Is color as we perceive it subjective?

Color as we perceive it is subjective, which means different people can see the same thing and think it looks different.

Imagine you and your friend are both looking at a piece of paper. You say it's blue, but your friend says it's green. That might sound strange, but it happens all the time, especially when the lighting changes. Like when you're outside in the sun or inside with a lamp. The same paper can look different under different lights because our eyes and brains work together to make sense of what we see.

Your brain is like a color detective. It uses clues from your eyes, like how bright something looks, or how it reflects light, to decide what color something is. But since everyone’s brain works a little differently, they might come up with different answers for the same clue.

So even though you both see the same paper, you can think it's blue or green, and that's totally normal!
