The Science of Light and Colour Mixing

Mixing red, green, and blue makes white. No, I'm not talking

about paint, I'm talking about light. These three are the primary colours

of light, and when they overlap, your eyes perceive the combination as white.

This is the secret behind every screen you look at. Your phone, your TV,

your monitor—they're all just millions of tiny red, green, and blue lights.

By mixing them in different intensities, they can create every colour imaginable. When red and green

light mix, you see yellow. When blue and green mix, you see cyan.

It’s called additive colour mixing.
