Which secondary colours are generally found on either side of red in a traditional colour wheel?

Correct answer: Orange and Violet

On the traditional artist’s colour wheel, red is positioned between orange and violet. Orange is the secondary colour made from red and yellow, while violet is made from red and blue. These two colours therefore lie on the adjacent sides of red and show its closest secondary-colour relationships. The other pairs either contain primary colours or do not occupy both neighbouring positions. Hence option D is correct.
