;; `tty-defined-color-alist' is created at startup by calling the
-;; function `tty-color-define', defined below, passing it each
-;; supported color, its index, and its RGB values. The standard list
-;; of colors supported by many Unix color terminals, including xterm,
-;; FreeBSD, and GNU/Linux, is supplied below in `tty-standard-colors'.
-;; If your terminal supports different or additional colors, call
-;; `tty-color-define' from your `.emacs' or `site-start.el'. For
-;; more-or-less standard definitions of VGA text-mode colors, see the
-;; beginning of lisp/term/pc-win.el.
