Set Canvas Color [SCv]

Set Canvas Color is used to set the color of the "workspace" - all the area beyond the defined pixels within an image (the DoD). This area usually extends to infinity. By default the canvas color used is Black / no Alpha (transparent).

Some tools may change an image's canvas color, e.g. inverting a mask will change the mask's canvas from black to white. Set Canvas Color allows you to control and override this.
