This should be straightforward: I want to style the matplotlib suptitle.
Documentation says that fontproperties is a dict of font properties that can be supplied as a parameter.
So:
import matplotlib.pyplot as plt
import matplotlib as mpl
fig, ax = plt.subplots()
ax.set_xlim(0, 1)
fdct = {'color': 'r', 'fontsize': 32}
# Generates error
fig.suptitle('A title', fontproperties=fdct)
# Works
fig.suptitle('A title', fontsize=32)
The first command generates
TypeError: FontProperties.__init__() got an unexpected keyword argument 'color'
But why? I would like to style suptitle with a dict of font properties, like I do for other instances of Text.

color is not a property of a font, it is a property of a Text (which, besides color, has a fontproperties property that is populated by suptitle with a FontProperties instance given its fontproperties dictionary argument).
suptitle returns the Text instance that it creates. You can change its color property either by using its set method with the color keyword argument, or more explicitly by its set_color method.
