Toon Ramp
The Toon Ramp controls the amount of detail in toon shading. It provides the positions for mapping a range of colors to the Toon material’s Diffuse channel or Specular channel, and the resulting color range is based on the hue set by that respective channel. You can add more positions to increase the number of colors in the range. The Toon Ramp is applied to the Toon Diffuse Ramp or Toon Specular Ramp of a Toon material node. The Toon Ramp can be accessed from the Materials category in the Node Graph Editor.

NOTE In order for the ramp's color values to be displayed on the surface, the Diffuse parameter in the Toon Material node needs to be set to a value of 1. This can be done using the default RGB Color parameter (node) or by relpacing the default node with another node that provides a 0 - 1 value. Otherwise, setting the Diffuse parameter to a color other than white (1), will affect the colors set in the Toon Ramp node. |
Toon Ramp Parameters
Interpolation - This determines how the colors blend.

Figure 5: Linear Interpolation
Interpolation Color Space - The color space in which colors are combined between control points. Physical uses linear values and creates gradients that approximate optical effects in the real world. Perceptual uses the Oklab color space and creates gradients that vary moothly to the human eye.
Start Value - The output value at the 0 position.
End Value - The output value at the 1.0 position.
Position 1 - A position that sets the boundary between the Start Value and the End Value.
Value 1 - The output value at position 1.
