to frame the main subject.

Monochrome describes paintings, drawings, design, or

photographs in one color or shades of one color. A

monochromatic object or image has colors in shades of

limited colors or hues.

The complementary color scheme is made of two colors

that are opposite each other on the color wheel. This

scheme looks best when you put a warm color against a

cool color, for example, red versus green-blue. The

complementary scheme is intrinsically high-contrast.

Analogous color schemes use colors that are next to each

other on the color wheel.
