Which is a correct sequence for remembering the traditional primary colours?

Correct answer: Red, yellow and blue

In the traditional painting model, the primary colours are red, yellow and blue, often remembered as RYB. These colours are treated as basic pigments rather than colours made by combining other painting colours, so option C is correct. Green, orange and violet are commonly classified as secondary colours produced by mixing pairs of primaries. Black, white, grey, pink and brown are not the traditional primary set.
