Thanks in advance for any help. I am trying to colorize b&w photos with the paintbrush and transparent colors. When I stop and start again the color goes on darker on the areas already painted, which messes the whole thing up, as seen in the attached photo. It's challenging to do a larger area continuously and impossible not to overlap when restarting. What do I need to do to have consistent color when I stop and continue over an already painted section?
