Get standard colors based on `colormap`, `color_type` or `color` inputs.
Parameters
----------
num_colors : int
Minimum number of colors to be returned.
Ignored if `color` is a dictionary.
colormap : :py:class:`matplotlib.colors.Colormap`, optional
Matplotlib colormap.
When provided, the resulting colors will be derived from the colormap.
color_type : {"default", "random"}, optional
Type of colors to derive. Used if provided `color` and `colormap` are None.
Ignored if either `color` or `colormap` are not None.
color : dict or str or sequence, optional
Color(s) to be used for deriving sequence of colors.
Can be either be a dictionary, or a single color (single color string,
or sequence of floats representing a single color),
or a sequence of colors.
Returns
-------
dict or list
Standard colors. Can either be a mapping if `color` was a dictionary,
or a list of colors with a length of `num_colors` or more.
Warns
-----
UserWarning
If both `colormap` and `color` are provided.
Parameter `color` will override.

Derive colors from either `colormap`, `color_type` or `color` inputs.
Get a list of colors either from `colormap`, or from `color`,
or from `color_type` (if both `colormap` and `color` are None).
Parameters
----------
color : str or sequence, optional
Color(s) to be used for deriving sequence of colors.
Can be either be a single color (single color string, or sequence of floats
representing a single color), or a sequence of colors.
colormap : :py:class:`matplotlib.colors.Colormap`, optional
Matplotlib colormap.
When provided, the resulting colors will be derived from the colormap.
color_type : {"default", "random"}, optional
Type of colors to derive. Used if provided `color` and `colormap` are None.
Ignored if either `color` or `colormap`` are not None.
num_colors : int
Number of colors to be extracted.
Returns
-------
list
List of colors extracted.

Single color is of these kinds:
- Named color "red", "C0", "firebrick"
- Alias "g"
- Sequence of floats, such as (0.1, 0.2, 0.3) or (0.1, 0.2, 0.3, 0.4).
