The Apply Gradient Map node provides remapping by interpolating color values.

Apply Gradient Map Parameters

Enabled - Whether this layer is applied or skipped.

Attach to layer - When selected, this layer modifies the input of the next lower layer that is not itself attached to a layer. Otherwise, it applies to the output of the next lower layer.

Interpolation type - Determines how the ratios of the input colors vary between control points.

Interpolation color space - The color space in which colors are combined between control points. Physical should be used for textures that contain non-color data, like normals.

  • Physical uses scene-linear values and creates gradients that approximate optical effects in the real world. 
  • Perceptual uses the Oklab color space and creates gradients that vary smoothly to the human eye.

Start value - Output value at 0.

End value - Output value at 1.

Opacity - The opacity channel used to control the transparency of this layer.

Blend mode - The blend mode used to mix the RGB values of this layer with those of the background.
