HueShift

HueShift transforms the input image’s colorspace. It works by transforming the colors to CIE XYZ space and then doing simple scales and rotates on the space. In XYZ space, X and Z control the color and Y is the brightness.

This node has an equivalent in Nuke.

Inputs and Controls

Connection Type	Connection Name	Function
Input	src	The image sequence to hue shift.
	mask	An optional image to use as a mask. By default, the effects are applied according to the value in the alpha channel of the mask.

Control (UI)	Knob (Scripting)	Default Value	Function
Type name	TypeName	HueShift	The node type.
Enabled	Enabled	ticked	If unchecked, this node will be omitted from the compiled image processing graph. Any incoming connections will be forwarded to the first output port, if any.
Label	Label	N/A	An optional label to display on the node.
Parameters
Reset parameters to default value using the reset icon: Switch between a single channel and separate channels:
Input greypoint	InputGreypoint	0.250	After converting to Cl E XYZ space, the colors are skewed so that this gray color is X = Z = 0.
Output greypoint	OutputGreypoint	0.250	After all other operations are completed, the CIE XYZ space is skewed to the output gray point so a fully desaturated image is tinted the specified color.
Overall saturation	OverallSaturation	1.000	Multiplies X and Z by the overall saturation value.
Colour axis	ColourAxis	Red: 1.000 Green: 0.000 Blue: 0.000 Alpha: 1.000	Adjusts the saturation in one direction in the XZ plane by setting this color axis. Adjust the saturation along axis control to affect the saturation.
Saturation along axis	SaturationAlongAxis	1.000	Adjusts the color saturation in the direction specified by the color axis control.
Hue rotation	HueRotation	1.000	Adjusts the rotation around the Y axis, which is mostly useful for making psychedelic effects.
Brightness	Brightness	1.000	Multiplies the image by the specified value.
