Yeah, it's kind of on the edge of being relatively neutral, i.e. not
standing out much more than the visible options, but I couldn't really
find anything that would work better for the standard 16-color mode.
An alternative would be to implement support for the 256-color mode,
but that would likely require quite a lot of changes in the existing
code (and I'm not very familiar with how to do it in ncurses...).
