The universal registry instance is `matplotlib.colormaps`. There should be no need for users to instantiate `.ColormapRegistry` themselves. Read access uses a dict-like interface mapping names to `.Colormap`\s:: import matplotlib as mpl cmap = mpl.colormaps['viridis'] Returned `.Colormap`\s are copies, so that their modification does not change the global definition of the colormap. Additional colormaps can be added via `.ColormapRegistry.register`:: mpl.colormaps.register(my_colormap) To get a list of all registered colormaps, you can do:: from matplotlib import colormaps list(colormaps) c<||_t||_dSN)_cmapstuple_builtin_cmaps)selfrs r'__init__zColormapRegistry.__init__Zs #Ellr)c |j|S#t$rt|ddwxYw)Nz is not a known colormap name)r.rKeyError)r1items r' __getitem__zColormapRegistry.__getitem__^sY O;t$))++ + O O OdCCCDD$ N Os!?c*t|jSr-)iterr.r1s r'__iter__zColormapRegistry.__iter__dsDK   r)c*t|jSr-)lenr.r9s r'__len__zColormapRegistry.__len__gs4;r)cFddd|DzS)Nz'ColormapRegistry; available colormaps: z, c3"K|] }d|dV dS)'N).0rs r' z+ColormapRegistry.__str__..ls*77$+d+++777777r))joinr9s r'__str__zColormapRegistry.__str__js-: 77$777778 9r)c t|S)z Return a list of the registered colormap names. This exists only for backward-compatibility in `.pyplot` which had a ``plt.colormaps()`` method.

The colormap name can then be used as a string argument to any ``cmap`` parameter in Matplotlib. It is also available in ``pyplot.get_cmap``. The colormap registry stores a copy of the given colormap, so that future changes to the original colormap instance do not affect the registered colormap. Think of this as the registry taking a snapshot of the colormap at registration. Parameters ---------- cmap : matplotlib.colors.Colormap The colormap to register. name : str, optional The name for the colormap. If not given, ``cmap.name`` is used. force : bool, default: False If False, a ValueError is raised if trying to overwrite an already registered name. True supports overwriting registered colormaps other than the builtin colormaps. r%zA colormap named "z" is already registered.z Re-registering the builtin cmap z is not allowed.zOverwriting the cmap z" that was already in the registry.N) rcheck_isinstancerColormapr ValueErrorr0 warn_externalrr.)r1r%rrHs r'registerzColormapRegistry.registerxs2 foD9999 ty 4<< >!GGGGIII,,, "=$("="="=>>>   Ct C C C D D D!IIKK D ;t  !T ) )%)DK  " " " * )r)ct||jvrtd|d|j|ddS)a Remove a colormap from the registry. You cannot remove built-in colormaps. If the named colormap is not registered, returns with no error, raises if you try to de-register a default colormap. .. warning:: Colormap names are currently a shared namespace that may be used by multiple packages. Use `unregister` only if you know you have registered that name before. In particular, do not unregister just in case to clean the name before registering a new colormap.
