:class:`~MDLabel` color:

:class:`~MDLabel` provides standard color themes for label color management:

To use a custom color for :class:`~MDLabel`, use a theme `'Custom'`.
After that, you can specify the desired color in the ``rgba`` format
in the ``text_color`` parameter:

.. code-block:: kv

    MDLabel:
        text: "Custom color"
        halign: "center"
        theme_text_color: "Custom"
        text_color: "blue"

.. image:: https://github.com/HeaTTheatR/KivyMD-data/raw/master/gallery/kivymddoc/md-label-custom-color.png
    :align: center

:class:`~MDLabel` provides standard font styles for labels. To do this,
specify the name of the desired style in the :attr:`~MDLabel.font_style`
parameter:

.. code-block:: python

    from kivy.lang import Builder

    from kivymd.app import MDApp
    from kivymd.uix.label import MDLabel
    from kivymd.font_definitions import theme_font_styles
