How to overlay lines onto map?
Hello all, and Merry Christmas.
I need some help with a project. The program I use only lets the user export the map backgrounds as one image and the lines and cities with a solid color background (that can be any color) like this:


(again, the red can be any color, not just red.)
Whenever I try to remove the red using the Color Range tool (Select>Color Range), it leaves a mess around the lines (probably because they have drop shadows on top of the red and such). This is the result:

Is there any other way I could remove the red background completely without the red shadows? Thanks in advance.
