Two-color gradient nail art in gold style refers to a nail art design where two different shades of gold are used to create a gradient effect. This style is popular for its elegance and versatility. It typically involves painting the base color on the nails and then gradually blending in a second shade to create a smooth transition from one color to another. Gold gradient nail art can be done using different techniques, such as freehand painting, nail art pens, or stencils.
