Suppose I have a document that I'm already working on, I know how to make the background black, but how do I change my font color (on screen)? Is there is a way to do it without changing all of my character styles?
I'm assuming that if I can figure that out, I should be able to do it for my template as well.
It will add an extra step, but there is a workaround. Duplicate the character styles you are using, and change the font color for the duplicates. Then before printing, you'll have to change them back.
It's a bit of a kludge, and can be quite unwieldy, but it's only workaround.
