Can't customise PDP plot colors

[lstodd]

It would be great to have the option to customise the PDPbox plot colours. Could this be added as a feature?

You can actually @lstodd. Check out the docs for the plot_params in most of the methods:
https://pdpbox.readthedocs.io/en/latest/target_plot.html

These are sent to matplotlib. Also plotting methods return figure and axes and you can use those matplotlib objects to do whatever you like. The docs have a handy reference here for one of the plot methods that should apply to the other ones that have the same parameter:
https://pdpbox.readthedocs.io/en/latest/pdp_plot.html

plot_params: dict or None, optional, default=None
parameters for the plot, possible parameters as well as default as below:

plot_params = {
    # plot title and subtitle
    'title': 'PDP for feature "%s"' % feature_name,
    'subtitle': "Number of unique grid points: %d" % n_grids,
    'title_fontsize': 15,
    'subtitle_fontsize': 12,
    'font_family': 'Arial',
    # matplotlib color map for ICE lines
    'line_cmap': 'Blues',
    'xticks_rotation': 0,
    # pdp line color, highlight color and line width
    'pdp_color': '#1A4E5D',
    'pdp_hl_color': '#FEDC00',
    'pdp_linewidth': 1.5,
    # horizon zero line color and with
    'zero_color': '#E75438',
    'zero_linewidth': 1,
    # pdp std fill color and alpha
    'fill_color': '#66C2D7',
    'fill_alpha': 0.2,
    # marker size for pdp line
    'markersize': 3.5,
