Ombré

Ombré (literally "shaded" in French) is the blending of one color hue to another, usually moving tints and shades from light to dark. It has become a popular feature for hair coloring, nail art, and even baking, in addition to its uses in home decorating and graphic design. In contrast to ombré, sombré is a much softer and gradual shading of one color to another.
