App Gradient Color Scheme

Quick answer：

An app gradient color scheme refers to the use of a gradient, which is a gradual transition between two or more colors, to design the interface of an application. This design technique is often used to create a visually appealing and cohesive aesthetic. Gradients can be horizontal, vertical, diagonal, radial, or even more complex patterns. They are popular in modern app design for their ability to add depth and a sense of movement to the user interface.
