Atmosphere Background Skill

Use When

• Create a dark atmospheric background with drifting vertical light folds, screen-blended glow, and a concentrated luminous corner or lower-edge bloom.

Workflow

Scope

• Apply this only to the immersive background layer, not to the full page layout, typography, or unrelated WebGL/particle systems.
• Use it when the design needs a moody atmospheric backdrop with fluid light curtains or folds instead of geometric grids, blobs, or literal illustrations.

Visual target

• Create a deep near-black background with soft vertical light folds drifting across the frame like illuminated fabric, fog sheets, or light curtains.
• Build the glow from multiple overlapping vertical bands so the background feels layered and spatial rather than flat.
• Let brightness accumulate more strongly toward one area, especially the lower right or lower edge, so the scene has a cinematic focal glow instead of uniform brightness.
• Keep the palette restrained: dark navy or charcoal base, then derive the glow from the design's primary color or strongest accent color. If no clear brand color exists, a cool cyan-blue atmosphere is acceptable.
