Houdini 20.5 Nodes VOP nodes

Color Correction VOP node

Provides a means to change the hue, saturation, intensity, bias, gain and gamma of the input color.

On this page

This operator provides a means to change the hue, saturation, intensity, bias, gain and gamma of the input color. Hue and saturation will not work on a greyscale input color. The changes cascade through the parameters in the order listed.

Inputs

Color In

The color to be corrected.

Hue Shift

This value is the distance and direction along the color wheel to shift the input color. However there must be some hue to start with. The value should be a number between -1 and 1.

Saturation

This value increases or decreases the saturation of the input color. However there must be some color to start with. Saturation is multiplicative, so zero saturation will return zero saturation.

Intensity

This value increases or decreases the intensity of the input color. Intensity is multiplicative, so black will return black.

Bias

This value increases or decreases the bias for any of the RGB channels of the input color individually. 0.5 is no change.

Gain

This value increases or decreases the gain for any of the RGB channels of the input color individually. 0.5 is no change.

Gamma

This value shifts the overall gamma of the input color. 1 is no change. Values less than 1 will “push” the color down and values greater than 1 will “pull” the color up.

Outputs

Color Out

The new corrected color.
