What is the main reason primary colours differ between painting and digital screens?

Answer and explanation

Correct answer: Their colour-producing processes are different

The governing concept is the difference between subtractive pigments and additive emitted light. Paint appears coloured because pigments absorb some wavelengths and reflect others, while a digital screen generates colour by emitting controlled red, green, and blue light. Consequently, their primary systems differ, so option A is correct. The other choices deny the role of colour or light and do not explain the physical reason for the difference.
