get_isosurface_colors

ifermi.plot.get_isosurface_colors(colors, fermi_object, spins, plot_index)

Get colors for each Fermi surface.

Parameters:

• colors (UnionType[str, dict, list, None]) –

  The color specification. Valid options are:

  • A single color to use for all Fermi surfaces, specified as a tuple of rgb values from 0 to 1. E.g., red would be (1, 0, 0).

  • A list of colors, specified as above.

  • A dictionary of {Spin.up: color1, Spin.down: color2}, where the colors are specified as above.

  • A string specifying which matplotlib colormap to use. See https://matplotlib.org/tutorials/colors/colormaps.html for more information.

  • None, in which case the default colors will be used.

• fermi_object (FermiSurface | FermiSlice) – A Fermi surface or Fermi slice object.

• spins (list[Spin]) – A list of spins for which colors will be generated.

• plot_index (list[int] | dict[Spin, list[int] | int] | int) –

  A choice of band indices (0-based). Valid options are:

  • A single integer, which will select that band index in both spin channels (if both spin channels are present).

  • A list of integers, which will select that set of bands from both spin channels (if both are present).

  • A dictionary of {Spin.up: band_index_1, Spin.down: band_index_2}, where band_index_1 and band_index_2 are either single integers (if one wishes to plot a single band for that particular spin) or a list of integers. Note that the choice of integer and list can be different for different spin channels.

  • None in which case all bands will be selected.

Return type:

list[tuple[float, float, float]]

Returns:

The colors as a list of tuples, where each color is specified as the rgb values from 0 to 1. E.g., red would be (1, 0, 0).
