Color gradient system

Quick answer：

A color gradient system refers to a range of colors that gradually transition from one color to another. This system is often used in design, art, and technology to create visually appealing and harmonious color transitions. In a color gradient system, the colors are arranged in a specific order, usually from light to dark or from lightest to darkest, to create a sense of depth and movement. This concept is fundamental in graphic design, photography, and digital art.
