I'm trying to set something to gray, but can't figure out how. The only bit of info in the man page about colors I can find is:
Set status line message background colour, where colour is one of:
black, red, green, yellow, blue, magenta, cyan, white, colour0 to
colour255 from the 256-colour palette, or default.
I also found a blog post which iterates through colors, but I can't quite grok it, and don't want to sit at the terminal all day guessing color numbers until one works.
