Which colour is mixed with blue to make violet?

Correct answer: Red

In the traditional art colour wheel, violet is a secondary colour formed by mixing the primary colours blue and red. Thus red is the required partner for blue, so option D is correct. Blue combined with yellow gives green, while green and orange are secondary colours and are not the standard primary-colour partner used to make violet in this lesson. Different proportions can alter the shade, but not the basic pair.
