Texture Paint - Can you invert Texture Mask?

Besides having/importing two texture/images…

Would be great if you could paint with one colour on part and with a different shade on the inverted part


You can use multiple shades/hues for a multi mask on a single image using separate rbg etc…, there’s also an invert node, expand a little on what you’d like to do.

I’d like to draw one part with white and then paint the part that is around it (with an inverted stencil) with a different colour …
