Monochrome means having or using only one color, or different shades of a single color. The word comes from Greek roots: mono meaning “one” and chrome meaning “color.”

A monochrome photograph uses only black, white, and the gray tones between them. Before color photography became common, all photographs were monochrome. Many photographers today still choose to work in monochrome because it can make images feel more dramatic or timeless, focusing attention on light, shadow, and composition rather than color.

A monochrome painting might use only blues, from pale sky blue to deep navy. An artist working in monochrome explores how much variety and interest they can create with just one color family. Computer screens and old video games were often monochrome: early Apple computers displayed everything in black and green, while others displayed only black and amber.

When designers talk about a monochrome color scheme for a room, they mean using different shades and tints of one color throughout the space. This creates a unified, harmonious feeling without the visual complexity of multiple colors competing for attention.
