Afterglow

Twelve colour fields burning above a dark horizon, built natively at 6K.

Rendered rather than photographed, so the gradients stay smooth right to the corners — no upscaling, no reconstructed detail. The grain goes on last, at full size, where it gives the flat colour some tooth.

Warm through cool, vivid through near-neutral. Monochrome for the days you want the desktop to disappear; Ultraviolet for the days you don’t.
