What 2 colors make purple?

If you mix two primary colors together you can create purple because purple is a secondary color. When you mix Blue and Red together you get Purple

Explanation:

Red and blue mixed together make purple. Red and blue are commonly mixed in identical parts, but greater red or blue are delivered for preference. Including white to this aggregate creates a lighter tint of purple, whilst adding black creates a darker shade of red.Red, blue and yellow are primary colors that occur naturally; they cannot be mixed from other existing colors. The secondary colors are purple, green and orange; they are formed from mixing two primary colors. A mixture of blue and yellow makes green, while a mixture of red and yellow makes orange. Tertiary colors are formed by mixing primary colors with secondary colors; red-violet and blue-green are examples of tertiary colors.
