why do computers use RGB rather than RYB to make all the colors?

Question

why do computers use RGB rather than RYB to make all the colors?

In: Physics

Answer 1

Paint is a thing where (for example) RYB mixed together create black.

Light is a thing where RGB mixed together create white.

(One of those is *additive* and the other is *subtractive*, but I’m never sure which is which. I do know that RYB are the primary colors for paint and RGB are the primary colors of light.)
