Value Node#

The Hue/Saturation/Value Node applies a color transformation in the HSV Color Model.

Inputs#

Factor: The amount of influence the node exerts on the image.
Image/Color: Standard color input.
Hue: The hue rotation offset, from 0 (-180°) to 1 (+180°). Note that 0 and 1 have the same result.
Saturation: A value of 0 removes color from the image, making it black-and-white. A value greater than 1.0 increases saturation.
Value: The value shift. 0 makes the color black, 1 keeps it the same, and higher values make it brighter.

Some things to keep in mind that might help you use this node better:

Hues are laid out on a circle: If you apply a Hue offset of 1 (+180°) to a blue image, you get the diametrically opposite color, which is yellow. If you apply a Hue offset of 1 to that yellow image, you get blue again.
Grayscale images have no hue: Trying to change the Hue or Saturation of a grayscale image has no effect. You can only brighten or darken it by adjusting the Value. To add color, use the Mix node instead.
Changing the effect over time: The different values can be animated using a Time Curve node or by setting keyframes.
