Which colour lies between red and orange on the colour wheel?

Correct answer: Red-orange

The correct answer is A, red-orange. A colour placed between two neighbouring colours on the colour wheel is often a tertiary colour named from both neighbours. Red-orange lies between red and orange and is made by combining those colours. Yellow-orange lies between yellow and orange, red-violet between red and violet, and yellow-green between yellow and green, so the other choices occupy different positions.
