Good morning everyone,

I would like to know how to invert the color between two lawers just like this below.

I tryed to mask one or the other but I'm having some trouble ..

Thanks in advance ..

Hi, create a layer,  fill it with white, or just a white outline, then sent its blending mode to Difference.

Yes, they should be a blending mode that does the same with black, what most users try, I think.
