;;; Commentary:
;;; Code:
(load "term/internal" nil t)
;;; This is copied from etc/rgb.txt, except that some values were changed
;;; a bit to make them consistent with DOS console colors, and the RGB
;;; values were scaled up to 16 bits, as `tty-define-color' requires.
;;;
;;; The mapping between the 16 standard EGA/VGA colors and X color names
;;; was done by running a Unix version of Emacs inside an X client and a
;;; DJGPP-compiled Emacs on the same PC. The names of X colors used to
;;; define the pixel values are shown as comments to each color below.
;;;
;;; 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
;;; an example.
