Tinting and shading are two ways of altering a color's overall appearance. To achieve a lighter color, tinting is used by adding as much white as needed to get the desired color. Tinted colors are also called pastels. Artists tint their paintings for softer effects. If an artist wants a darker hue, he or she will shade the colors. A shade is the opposite of a tint; instead of adding white, black is added to the color. Artists use black cautiously because it can quickly overwhelm the original color.
