Trapezoidal gradient nail art refers to a design technique where the color or pattern gradually transitions from one shape to another, resembling a trapezoid. This style is popular for its unique and eye-catching appearance, often used in nail art to create a visual effect that draws attention. It involves carefully applying different colors or patterns in a way that the transition from one color to another forms a trapezoid shape. This type of design requires precision and artistic skill to achieve a professional look.
