ipython in emacs with dark background

I use a black bg color theme in emacs,while ipython outputs like this by default:

 

well,some part of the output is black,it sucks

after a travel in the source code of ipython.el and python-mode.el,I found that ipython.el add a "-color lightbg" to command args when start ipython by default,as following:


(unless (member "-colors" py-python-command-args)
(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"))))))

so I can either modify the py-python-command-args variable or frame-background-mode variable to stop it sucking.

I choose the latter one.

 

BTW:both ways the variable must be set before ipython.el is loaded,for the code above is runned while loading rather than in a function which runned later.
