The three primary colors are red, blue and yellow. Primary colors, by definition, are the only colors that CANNOT be made by mixing two other colors. All other colors can be derived by mixing two or more colors. Since red color is one of the three primary colors, it cannot be made with a combination of other colors. But if you have red, you can make it light red or dark red. Red mixed with a small amount of white makes it a light red shade. Red mixed with a small amount of black makes it a dark red shade.
