Varieties of the color red may differ in hue, chroma (also called saturation, intensity, or colorfulness), lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a red or other hue mixed with white, a shade being mixed with black. A large selection of these various colors are shown below.
