fun piece of #htop trivia: I don't think I've ever seen an htop screenshot use this color theme (and neither do I use it), but from the very first version that supported themes, I've included this very MS-DOS-inspired "MC" theme as a tribute to @Migueldeicaza's Midnight Commander. MC's builtin editor "mcedit" was _fundamental_ to me when I first got into to #Linux back in... err, 1999?
The first versions of htop from 2004 to 2006 were all written in mcedit!
