Color/HSV Transformation
 
 

HSV Transformation is a powerful function, which allows you to modify the texture's HSV color channels with the help of mathematical expressions.

Each color channel is changed by its own expression. The input values H,S and V are based on the texture's old pixels. X and Y reflect the pixels' coordinates, ranging from 0 to 1.

Image 4 for instance was created by setting H=Y, which means that the vertical coordinates are translated to the hue of the new colors. The saturation S was set to 1 for the entire texture (S=1). The brightness remained unchanged (V=V or an empty field for V).
