Background color gradient on poster

Quick answer：

A background color gradient on a poster refers to the transition between two or more colors that creates a smooth blend from one color to another. This technique is often used to enhance visual appeal and convey a specific mood or theme. In graphic design, creating a gradient involves selecting colors, defining the gradient type (linear, radial, etc.), and adjusting the blending mode. Gradient backgrounds are popular in poster design for their ability to draw attention and create a visually interesting composition.
