Why do printers combine cyan, magenta and yellow to create a colour image while video displays like TVs and Monitors use Red, Green and Blue?

The difference is additive vs subtractive colour mixing.
– Mixing all colours of light makes white.
– Mixing all colours of paint makes brownblack.
It’s like that because “white light” is a mix of all the colours. Video screens shine the colours of light that you see.
Paintprintersink work by absorbing all the colours of white light *except* the colours you see. Red ink absorbs all the colours except red, and bounces the red part to your eye. Same for blue etc.
That’s why colour mixing works differently for screens vs ink pigments. Screens are adding light together. Ink is removing different combos from white light hitting the printed object and you see what’s left.
