当我在X终端窗口中运行emacs -nw,并且我要求M-x列表颜色显示时,我提供了一个微不足道的调色板：
black red green yellow blue magenta cyan white
我被告知可以获得265种颜色.将TERM环境变量设置为xterm-256color不起作用.什么
解决方法
根据
this,除了将TERM设置为xterm-256color之外,还需要ncurses-term库.
好的,this还有其他一些尝试：
The xterm in Ubuntu Edgy does not advertise 256 color support by
default. To fix this you need to install a 256 color terminfo entry,and tell xterm to use it:
apt-get install ncurses-term
echo XTerm.termName: xterm-256color \
>>~/.Xdefaults
xrdb -merge ~/.Xdefaults
并且：
So you need a file term/screen-256color.el in your load-path. Emacs
22 expects it to contain a terminal-init-screen defun. Emacs 21
expects it to contain a bunch of top-level forms. Here's what I use:
;;; This is for GNU Emacs 22
(defun terminal-init-screen ()
"Terminal initialization function for screen."
;; Use the xterm color initialization code.
(load "term/xterm")
(xterm-register-default-colors)
(tty-set-up-initial-frame-faces))
;;; This is for GNU Emacs 21
(if (= 21 emacs-major-version)
(load "term/xterm-256color"))
For Emacs 21,you also need to install the xterm-256color.el file from
