Which colour lies between blue and red on a colour wheel?

Correct answer: Violet

The governing concept is the relationship between primary and secondary colours on a traditional colour wheel. Blue and red are primary colours, and their mixture produces violet, also called purple in many art contexts. Violet is therefore placed between blue and red. Green is between blue and yellow, and orange is between red and yellow, so options C and D describe other pairings. Option B is correct.
