What should be checked first if two colours do not produce the expected secondary colour?

Answer and explanation

Correct answer: Purity of colours and mixing ratio

The governing concept is troubleshooting a colour mixture by checking its inputs before changing unrelated conditions. Impure or incorrectly identified paints, together with an unsuitable ratio, can prevent the expected secondary hue from appearing. Option D is correct because both pigment quality and proportion directly affect the result. Paper length, artwork title, and room size do not alter the chemical or visual relationship of the two mixed colours.
