rcParam for 3D pane color

The rcParams rcParams["axes3d.xaxis.panecolor"] (default: (0.95, 0.95, 0.95, 0.5)), rcParams["axes3d.yaxis.panecolor"] (default: (0.9, 0.9, 0.9, 0.5)), rcParams["axes3d.zaxis.panecolor"] (default: (0.925, 0.925, 0.925, 0.5)) can be used to change the color of the background panes in 3D plots. Note that it is often beneficial to give them slightly different shades to obtain a "3D effect" and to make them slightly transparent (alpha < 1).

import matplotlib.pyplot as plt
with plt.rc_context({'axes3d.xaxis.panecolor': (0.9, 0.0, 0.0, 0.5),
                     'axes3d.yaxis.panecolor': (0.7, 0.0, 0.0, 0.5),
                     'axes3d.zaxis.panecolor': (0.8, 0.0, 0.0, 0.5)}):
    fig = plt.figure()
    fig.add_subplot(projection='3d')
