What is the form produced by adding white to a primary colour called?

Correct answer: Tint

The governing concept is the modification of colour value. Adding white to a colour produces a tint, which is a lighter version of the original colour. For instance, white mixed with red produces a light red or pink tint. A shade is produced by adding black, while a tone is commonly produced by adding grey or a neutral colour. A complement is a colour relationship, not a lightened mixture, so option B is correct.
