Gradient nail art involves seamlessly blending two or more colors across the nail, typically from one side to the other, creating a smooth transition between the hues. This method often uses a sponge to apply the colors, ensuring a gradual and continuous blend.

Choose 2 colors of flat nail polish that look nice when mixed together. For best results, choose 2 primary colors, or a primary color and a related secondary color. For example, you could do blue and yellow or pink and purple.

Gradient nails (aka "Skittles" or rainbow nails) involve painting each nail a slightly different shade of a similar color, or different, complementary colors. If you choose pink, for example, you might paint the first nail a soft and powdery hue.
