What It Does
Map Ramp generates color gradients by mapping them to grayscale sources. You choose which channel to use as the gradient base (Red, Green, Blue, Alpha, or Lightness), then build a gradient with multiple color knots. The plugin maps those colors across the tonal range of your source layer.
It works equally well for color correction (remapping tones in footage) and creative work (building custom color treatments or mattes from scratch).
Key Features
Six interpolation modes. Linear gives standard blends, with a Hardness slider for sharp transitions. Variable mode offers smooth ease-ease curves or sharp color breaks. Bezier uses up to four control points for smooth blending between knots. B-spline provides natural interpolation across any number of knots without the four-point rule.
Knot controls. Each knot has Position, Color, Alpha (adjusts pixel alpha at that point), and Blending (mixes the knot color with the source color). Visual indicators on the ramp show position and color directly, with small points representing alpha and blend values.
Effect-level controls. Blend With Original mixes the gradient back with the source layer. Blend Alpha Also reverts alpha changes to preserve the original transparency.
Transform parameters. Cycle the ramp, offset the origin, and apply additional transforms added in version 1.1.
UI tools. Select previous/next knot, distribute knots evenly (local or global), and flip the ramp.
Who It’s For
Color graders who need precise control over how colors map to tonal ranges. Motion designers building custom color treatments or matte effects. Anyone working with grayscale sources (like luma mattes or displacement maps) who wants to convert them into color gradients with specific blending behaviors.
