mne.viz.plot_source_estimates docs incorrectly say colormap can be supplied as an ndarray #13189

Proposed documentation enhancement

The docs on the website include:

colormap : str | np.ndarray of float, shape(n_colors, 3 | 4)

• Name of colormap to use or a custom look up table. If array, must be (n x 3) or (n x 4) array for with RGB or RGBA values between 0 and 255. The default (‘auto’) uses 'hot' for one-sided data and ‘mne’ for two-sided data.

But then in _process_clim there is a call to _validate_type(colormap, (str, Colormap), "colormap"), which throws an error if an ndarray is supplied.
