Color schemes are the choice of colors used in design. The most basic and default color scheme is the use of a white background with black accents. Color schemes create style and appeal, as well as an aesthetic feeling when the colors used accompany each other well. A basic color scheme uses two colors that look appealing together. Other color schemes combine several colors, usually based around a single color, like red, yellow, and orange, or different shades of a single color.
