IPython doesn't use colorama at all, but I believe it and pyreadline (which
IPython does use) both try to interpret ANSI escape codes and do the
appropriate operations (e.g. changing colours) in the Windows console.
Presumably if they're both active and trying to do the same thing, they
conflict in some way.
