gray-scale color combination

Quick answer：

Gray-scale color combination refers to the use of shades of gray in various tones to create harmonious and visually appealing designs. It is commonly used in art, graphic design, and fashion, where the absence of color can evoke a sense of sophistication and timelessness. Gray-scale combinations can range from monochromatic, where all shades of gray are used, to various shades and tints, which include white and black. The key to effective gray-scale color combinations lies in understanding the color wheel, value (lightness/darkness), and harmony (complementary, analogous, triadic, etc.).
