The Science Behind Muted Colors Muted colors are created by reducing the saturation of hues, making them less vibrant and more subdued. This is achieved by mixing a color with grey, white, black or its complementary color. For example, adding grey to yellow creates a dulled mustard tone, while mixing orange with blue reduces its intensity to a warm brown. On the color wheel, muted tones sit between bright, saturated colors and neutral tones.
