+;;; If you want to change the RGB values, keep in mind that various pieces
+;;; of Emacs think that a color whose RGB values add up to less than 0.6 of
+;;; the values for WHITE (i.e. less than 117963) are ``dark'', otherwise the
+;;; color is ``light''; see `frame-set-background-mode' in lisp/faces.el for
