Which statement is correct because blue is itself a primary colour?

Correct answer: In traditional colour mixing, blue is not made from other primary colours

In the traditional school paint-pigment model, blue is classified as a primary colour. This means it is treated as a basic colour that is not produced by mixing the other primary colours, so option B is correct. Yellow and red make orange, not blue. The remaining combinations may create dull or uncertain results depending on pigments, but they are not the standard explanation of how primary blue is obtained.
