AURORA BOREALIS — POLAR LIGHT CURTAINS

VISUAL STYLE: Aurora Borealis as animation aesthetic. Vast curtains of ionised light rippling across polar skies — green, violet, and white light folding and unfolding in slow waves above a dark landscape.

COLOUR PALETTE: Deep black sky as the primary ground. Luminous green as the dominant aurora colour — the specific green of oxygen ions at 100km altitude. Deep violet and magenta for higher altitude emissions. White where colours overlap and intensify. Pale silver-blue for foreground ice and snow reflecting the aurora light above.

LIGHT: The aurora IS the light source. No sun, no moon — only the curtains above, casting their moving green-violet light downward onto a frozen landscape.

MOVEMENT: The defining quality — slow, wave-like folding of light curtains. Ripples moving along the curtain from one edge to another. The occasional sudden brightening — a substorm — where the whole sky intensifies for a moment before settling back.

LANDSCAPE: Minimal and dark — a horizon line, a frozen lake surface, silhouetted trees at the very edge of the frame. The landscape exists only to give scale to the sky. The sky is everything.

No daylight. No urban light. No artificial sources. Only the sky, the ice, and the impossible light between them.
