Three gradient color palettes

Quick answer：

A gradient color palette consists of a series of colors that transition smoothly from one to another. These are often used in graphic design, web design, and digital art to create a sense of depth, continuity, or visual interest. There are various types of gradient color palettes, such as linear gradients, radial gradients, and conical gradients. Creating a gradient palette involves selecting a base color scheme and then adjusting the color transitions to achieve the desired visual effect.
