What type of colour is yellow in the light system?

Answer and explanation

Correct answer: A secondary light colour made from red and green

The governing concept is the additive RGB light system, in which red, green and blue are the primary light colours. When red and green light overlap, their wavelengths stimulate the eye together and are perceived as yellow. Therefore yellow is a secondary light colour, making option B correct. Green plus blue produces cyan, while option D refers to pigments rather than emitted light.
