Between which two colours is blue-violet located on the colour wheel?

Correct answer: Blue and violet

The governing concept is the placement of a tertiary colour between its neighbouring colours. Blue-violet lies in the section between blue and violet on the colour wheel, so option B is correct. Yellow-orange belongs between yellow and orange, yellow-green between yellow and green, and red-orange between red and orange. Therefore none of those alternative pairs describes blue-violet’s position.
