I'd like to change the colors. The lime green hilighting on pale blue colored file names is killing my eyes.

I'm not sure if I'm using `xterm` or `gnome` or whatever, but I would like to change the default color scheme (preferable to something less offensive to my corneas) and have it stay changed (update my user profile).

Colors are nice, but sometimes it makes the text unreadable. I would settle for having no colors, standard B&W, if I can't have nice colors.
