Sorry to repeat myself but:
   a) providing example code would clarify what you are doing.
   b) wxmplot might do what you want.
   c) even if not, the wxmplot code will show you an example of one way
this can be done.
   d) wxmplot sets rcParams **and** sets the colors of the plot components.

See: https://github.com/newville/wxmplot/blob/master/wxmplot/config.py#L313
