Theory & harmony

Additive color

Color made by adding light. Red, green and blue light combine toward white; screens work this way.

Also called additive color mixing, additive colour

Additive color starts from darkness and adds light. Mix red, green and blue light at full strength and you get white; take them all away and you get black.

Every screen is additive: each pixel is three tiny lights, and a color like #2387FF is just a recipe for how bright each one is. That is why screen colors can glow in a way printed colors cannot.
