The gradient, multicolored series of glitter is a decorative material that achieves a natural color transition through a special process. It is widely used in nail art, cosmetics, fashion accessories, and art creation. Its core feature is the use of particle size, color overlays, or optical reflection techniques to create a gradient effect from light to dark or between different color schemes. The charm of gradient glitter lies in the dance between material and light—from millimeter-scale nail art to nanometer-scale mother-of-pearl makeup, all use "gradient" as the language to interpret the flowing brilliance.
