Gradient nail art is a popular and creative nail design technique that involves blending different colors in a smooth, gradient transition. It can range from subtle to bold, and can be customized to various themes or seasons. To create gradient nails, one typically starts with a base color, applies a second color in a thin layer, and then gradually blends the two colors together for a seamless look. This style requires a steady hand and sometimes the use of specialized gradient brushes or strips to achieve the desired effect.
