When are primary colours taught in basic colour education?

Correct answer: At the beginning stage

The governing concept is the sequence of learning colour theory. Primary colours—traditionally red, yellow and blue in painting—are foundational because learners use them to understand colour mixing and the formation of secondary colours. Therefore, they are introduced at the beginning, making option B correct. Option A is incorrect because advanced colour relationships come later, while options C and D wrongly exclude basic school learning.
