If orange is placed between blue and red on a colour wheel what correction is needed?

Correct answer: Place it between red and yellow

The governing rule is that each secondary colour is placed between the two primary colours that produce it. Orange is made by mixing red and yellow, so it belongs between red and yellow on the colour wheel. Green belongs between yellow and blue, and violet belongs between blue and red. Therefore option D is correct; option C describes the correct position of green, not orange, while the other choices are also unsuitable.
