More colors on Mac OS X

[Matthew Calhoun <calhounm@mac.com>]

Hello,

I'm using Mac OS 10.2.2 and the Emacs that came with it (21.1) in tcsh 
in the Terminal application. I'm attempting to use syntax coloring, 
with limited success.

I have this:

(global-font-lock-mode t)
(setq font-lock-maximum-decoration t)
(set-background-color "Black")
(set-foreground-color "White")
(set-cursor-color "White")
(custom-set-faces
'(font-lock-comment-face ((((class color) (background dark)) 
(:foreground "yellow"))))
...

in my .emacs file, and I've set my TERM environment variable to 
"xterm-color". Now I'm getting color, but the only colors available 
seem to be Red, Green, Blue, Cyan, Magenta, Yellow, Black, and White. A 
call to list-colors-display confirms this. Does anyone have any advice 
on how to get more colors (without switching to XEmacs)?

Thanks,
Matt
