Displays are not made of paint, though - they use light. There are two models of combination: - subtractive, which applies to paint, since the more you mix in the more frequencies are absorbed - additive, which applies to light, as mixing an extra light adds the frequencies in it So additive, where more colour tends to white, is correct.
