Color/RGB Transformation
 
 

RGB Transformation works similar to the HSV Transformation, but takes place in the RGB color space. You can utilize it to perform non-linear color operations, like reciprocal scaling to create mountain heightmaps from different noise textures.

The RGB color channels are modified separately by their own expressions. The R, G and B variables originate from the color values of the old pixels. X and Y represent the pixels' coordinates.
