Which two primary colours are mixed to make green?

Correct answer: Yellow and blue

In the traditional pigment colour system, yellow and blue are mixed to produce green, so option B is correct. Red and yellow produce orange, while red and blue produce violet or purple. Green is called a secondary colour because it is formed by combining two primary colours. The exact shade may vary with the pigments and their proportions, but the basic classroom colour-wheel relationship remains yellow plus blue equals green.
