3D Gradient Square Luminous Frame Background Material

Description

Centered on a geometric square, this image creates a visual illusion of a recessed space through multi-layered gradients and perspective. The innermost layer is a clear cyan-blue, which gradually blends outward into light purple, then pinkish-purple, and transitions to deep black at the outermost layer. The soft glow makes the square resemble a luminous tunnel, with light and shadow flowing together to merge a sense of technology and dreaminess. The geometric order and gradient colors are perfectly integrated, and it can serve as a background material for creative posters, web design, or design templates, adding a unique luminous aesthetic to your works.
