This looks like emacs problem. Are you sure that emacs was compiled
with 256 color support? (at least I know that elinks can be configured
to support 88 and/or 256 and/or real colors)
Also is there some kind of termcap option in emacs to be changed/read?
I dont use emacs but in vim:
:set t_Co=256
will show 256 colors if terminal supports it.
Actually if t_Co termcap setting is N, vim will not try to show more
than N colors even if terminal supports X(>N) colors.
