Color gradient value

Quick answer：

A color gradient value refers to a range of colors that transition smoothly from one color to another. It is commonly used in design and digital art to create visual effects like smooth transitions or gradients in images and user interfaces. In programming, color gradients can be represented using hexadecimal codes or RGB(A) values, where the values change gradually from one extreme to another, like from 0 to 255 in the RGB model.
