Holographic Gradient Poster

Quick answer：

A holographic gradient poster is a type of poster that utilizes holographic technology and gradient color effects to create an illusion of depth and a smooth transition of colors. These posters are often used in advertising and design to attract attention and convey a sense of modernity. Holographic elements can include 3D images or effects that seem to float off the surface, while gradient colors provide a visual appeal that changes as the viewer's angle shifts.
