How to make red
Know that you cannot make red.
Red is a primary color, so you cannot create it by mixing any other colors.
Primary colors are colors that exist on their own and do not contain traces of any other color.
Aside from red, the other primary colors are blue and yellow. Even though you cannot make pure red, you can still make other hues of red by mixing pure red with other colors.
