Colour that blooms.

THE SYSTEM BEHIND THE SURFACE

Inside Grain Bloom.

Soft blooms of colour are laid over a deep ground, far to near, each a translucent swell with a soft edge: a blue to the left, a red behind at the top, an orange in front at the lower right, a peach and a pale glow in the upper right. The colours are blended in OKLab with their chroma held, so blue meets red through violet and red meets orange through coral, never through grey. A slow flow folds the field, so the boundaries drift and curl. Each bloom is lit as a gentle dome by the glow in the upper right, which gives the colour body, and a fine film grain finishes the surface and keeps the long gradients from banding. The cursor stirs the colour around itself and draws the light toward it.

Grain Bloom is an abstract colour field, not a photograph or a 3D scene: there are no objects, reflections or real depth of field, and it does not take your images. Its grain is a fixed film texture, not a model of a camera's noise.
