Gradient Map

Remap luminance through a custom colour gradient.

Gradient maps replace luminance with colours along a ramp. Poster designers and finishing artists use them to force a controlled palette while keeping photographic structure.

Two stops make a duotone; more stops build cinematic or graphic grades with clear colour intent.
