Shades of black are colors that differ only slightly from pure black. These colors have a low lightness. From photometric point of view, a color which differs slightly from black always has low relative luminance. Variations of black include what are commonly termed off-black colors, which may be considered part of a neutral color scheme, usually in interior design as a part of a background for brighter colors. Black and dark gray colors are powerful accent colors that suggest weight, dignity, formality, and solemnity.
In color theory, a shade is a pure color mixed with black. It decreases its lightness while nearly conserving its chromaticity. Strictly speaking, a "shade of black" is always a pure black itself and a "tint of black" would be a neutral gray. Unlike these, many off-black colors possess a hue and a colorfulness (also called saturation).
Colors often considered "shades of black" include onyx, black olive, charcoal, and jet; these colors and other variations of black are shown below.
