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. -- Paul
