What problem does it solve? Designing a moody, cinematic dark background often results in flat gradients or generic blobs that lack depth and motion. This Skill provides concrete guidance for building layered, animated atmospheric backgrounds with vertical light folds and a focused luminous bloom. ## Core Features & Use Cases - Layered light folds: Build multiple overlapping vertical bands with slow sine-wave drift and screen/additive blending so the background reads as moving atmospheric light rather than static columns. - Focal glow control: Concentrate brightness toward a corner or lower edge with a radial glow overlay, creating a cinematic focal point instead of uniform brightness. - Palette discipline: Derive the glow from the design's primary accent color over a dark navy or charcoal base, avoiding loud rainbow transitions. - Use Case: When building a landing page hero section that needs a premium, moody backdrop, apply this Skill to render a canvas or shader-driven background with drifting cyan-tinted folds glowing toward the lower right corner. ## Quick Start Create a dark atmospheric background for my hero section with slowly drifting vertical light folds and a soft glow concentrated in the lower right corner.
