What is formed by adding white to a secondary colour?

Correct answer: A lighter tint of the same colour

In colour mixing, adding white to an existing colour produces a tint. The colour becomes lighter while remaining in the same colour family; for example, white added to orange creates a lighter orange or peach-like tint. A shade is darker and is generally made by adding black. White does not convert a secondary colour into a primary or complementary colour, so option A is the only correct answer.
