I recently changed some of the colours, using tuples of RGB values instead

This has probably nothing to do with the way you specify colors. For
some reason matplotlib is using an interactive backend. Make sure that
your script starts with
import matplotlib
matplotlib.use('Agg')
or that you specify the Agg backend in your matplotlibrc file.
