Which color scheme involves two or more neutral colors enhanced by a single color?

The choice involving a color scheme that combines two or more neutral colors with a single accent color is referred to as an accented neutral color scheme. This approach allows for the elegance and subtlety of neutral colors, while the addition of a vibrant or bold accent color introduces a focal point or visual interest. This technique is commonly used in fashion and interior design, as it creates a balanced and sophisticated aesthetic. By relying primarily on neutral tones, such designs can evoke a sense of calm and unity, while the single accent color provides some contrast and excitement, making the overall look more dynamic.

The other options relate to different color relationships that do not primarily focus on the use of neutrals with a sole accent color. For instance, a triadic scheme involves three colors evenly spaced on the color wheel, creating a vibrant and dynamic combination, while an analogous scheme consists of colors that are next to each other on the color wheel, resulting in a more harmonious gradient of colors. A monochromatic scheme, on the other hand, relies on variations in lightness and saturation of a single color, rather than the combination of multiple neutrals.
