Which colours are considered primary in traditional painting?

Correct answer: Red, yellow and blue

The governing concept is the traditional pigment colour model used in elementary painting instruction. In that model, red, yellow, and blue are identified as primary colours and are used as a base for producing secondary mixtures. Therefore option A is correct. Green, orange, and violet are commonly taught as secondary colours; black, white, and grey are neutral colours, while brown, pink, and gold are not the standard primary set in this model.
