About Map Ramp

Map Ramp creates a gradual blend between multiple colors, using a grayscale source as the base to map the gradient. Any of five channels—red, green, blue, alpha, or lightness—can drive the mapping. The effect offers several interpolation modes: Linear with a Hardness control, Variable with a Nonlinearity control, Bezier supporting up to four points, and B-spline with an unlimited number of points. Each knot stores its own Position, Color, Alpha, and Blending values, while effect-wide settings include Blend With Original and Blend Alpha Also. Additional options let you select knots and flip their positions. The plugin is compatible with After Effects 2025 back through CC 2017.
