Pete> Colors are set by a command line option to ipython. I used Pete> customize to set `py-python-command-args': Pete> Value: ("-pylab" "-colors" "LightBG") Pete> I think that the options for -colors are NoColor, Linux, and LightBG. My last input on this (maybe this is mostly for the XEmacs folks and Alexander Schmolck - author of ipython.el - but I don't have an email for him handy). I looked at the color-option-setting code in ipython.el and found this: (setq py-python-command-args (nconc py-python-command-args (list "-colors" (cond ((eq frame-background-mode 'dark) "Linux") ((eq frame-background-mode 'light) "LightBG") (t ; default (backg-mode isn't always set by XEmacs) "LightBG")))))) Then I ran "xemacs -rv" and evaluated frame-background-mode. It was still 'light. I don't know what the right variable to test is, but on XEmacs it doesn't appear that the -rv command line flag causes frame-background-mode to be set differently (this is in 21.5b28).
