there are many "themes" packages, some quite fancy.  below is a simple
one.  i load this on startup, and call `set-theme' from ~/.emacs, which
is early enough to make the mysterious (to me) font-lock machinery DTRT
for things like `font-lock-function-face', etc.  back when i was loading
it later in the session, sometimes font-lock would make disturbing color
choices.
