Using the "color" command, you can tell mutt how to dress. Let's say you have quite a lot of those color commands in your configuration, preferably in a separate ~/.mutt/colors file.
Is there a way to tell mutt in the configuration that the color "default" is to appear as "black"? Note that "default" is bound, at least by default, to the background color of your terminal. I changed that terminal background color, but now my mutt colors aren't to my liking any more, which prompted me to think about the best way to configure colors. It would be convenient if I could have a layer of indirection and define "default" to be black in the mutt configuration. If not, in order to be flexible and switch color schemes without global search and replace, I could make the color file a template containing placeholders like [% default %] or [% hilite %] or [% error %], thus obtaining a layer of indirection, and process it using my color definitions du jour to achieve the desired result.
