Gradual nail art, also known as ombre nail art, features a smooth transition of color from light to dark or vice versa. Popular gradual nail art styles include pastel to neon, solid colors, and metallic or holographic finishes. When choosing a gradual nail art design, consider your personal style and the season. For example, lighter shades like pink, lavender, or sky blue are suitable for spring and summer, while darker, richer colors like deep red, emerald green, or plum work well for fall and winter.
