John,
I've looked through the IPython documentations and it looks like the colors
can only be controlled by the configuration files only, or they can be set
by a command line argument to IPython upon startup, but it looks like it
won't be possible to do it on the fly. However, I've been having trouble
finding a centralized location where the command line arguments are
handled; would you be able to provide any guidance?
Thanks,
Nitin
