Which group correctly contains the primary colours?

Correct answer: Red, yellow, blue

Within the traditional painting colour model used in school art education, red, yellow, and blue are taught as the primary colours. They serve as basic colours for mixing secondary colours: yellow and blue can produce green, red and yellow can produce orange, and red and blue can produce violet. Thus option A lists secondary colours, while the other groups are mixtures or non-primary descriptive colours. Option B is correct.
