Remap HSV

Lets you adjust the color output of nodes. It converts an RGB input to HSV, remaps using separate HSV gradients, then converts the result to a color output.

With this utility, you can fine-tune or completely change the hue, saturation, and luminance of a color with the provided gradients. For example, you could connect the outColor of a file texture to the color (input) attribute on remapHsv, then connect the remapHsvoutColor to your shader color. By editing the gradients you could then modify the brightness range or hue of the file texture with a great deal of control:

You can make the image black and white make the saturation graph all zero.
You can invert the brightness for an x-ray effect make the value graph 1 at the left and zero at the right.

You can also remap the color of a shader by connecting the outColor of the shader into remapHsv.color then connecting remapHsv.outColor the outColor of a surface shader node. The surface shader then becomes a color correctable version of the original shader.

Note:

The surface shader performs no calculations directly, it is simply a placeholder for a shading outColor attribute.
