more compact, colorful output

maybe a bit too strong?

avoided blue because most default themes render that unreadable on dark
backgrounds. went with cyan instead which is pretty safe.

avoided bright colors because people think solarized is a good theme and it
replaces all bright colors with dark blue. (cool.)

avoided dim text because iTerm doesn't support the escape code and it's
otherwise impossible to pick light grey or white because some people use black
on white and some use white on black.

picking colors is hard. hopefully this works for everyone.
