Saturate

Parameter Types

Parameter descriptions

In

The input color to adjust the saturation of.

Amount

The multiplier to apply to the saturation; the default value is 1.0.

Luma Coefficients

The luma coefficients of the color space. The possible values for this node are the luma coefficients for the color spaces acescg, rec202/rec2100, or rec709. The default value is the luma coefficients for acescg, which are (0.2722287, 0.6740818, 0.0536895).

Discussion

The Saturate node performs a linear interpolation between the incoming color value and the luminance of the incoming color value. Setting the value of the Amount parameter to 0 adjusts the output to a grayscale of the input equal to the value that the Luminance outputs.

Below is an example of a simple node graph that uses the Saturate node to modify the saturation of an image:

Below, the resulting texture applies to a cube:
