What is the term for an outfit or display in which everything is the same color or hue?

The term that describes an outfit or display in which everything is the same color or hue is known as a monochromatic color scheme. This approach utilizes various shades, tints, and tones of a single color to create a cohesive look that can be sophisticated and harmonious. By focusing on one color, a monochromatic scheme allows for the exploration of color depth and texture while maintaining a unified aesthetic.

In contrast, other color schemes involve different combinations of colors. A complementary color scheme features colors that are opposite each other on the color wheel, creating a striking contrast. An analogous color scheme combines colors that are next to each other on the wheel, offering a more blended and less dynamic appearance. A triadic color scheme uses three colors that are evenly spaced around the color wheel, resulting in a vibrant palette. Each of these alternatives serves different purposes in design and styling but does not achieve the singular focus that a monochromatic scheme does.
