A comic shading auto action set to make the process more efficient!
There will be two new and one color altered layer after the action is run.

-The solid color and blurred image are meant to be clipped onto the shading layer.
-The blurred image is meant to be airbrush erased for a natural effect.
-(If you do not like the look of it, you may also just get rid of the blurred layer)
These are the colors I often end up using in my comics, so not all types of lighting scenarios are here, but I hope it will prove useful still!
