Simple gradient nail designs are a popular trend in nail art, featuring subtle transitions of color that create a sleek and modern look. These designs typically use a combination of two or more colors, blending them seamlessly from one hue to another. The key to a successful gradient nail design lies in the smooth application of the polish and the choice of complementary colors. Gradient nails can be done on natural nails or artificial nails, and can range from subtle pastels to bold, vibrant shades.
