Customizing the UI
==================

.. _customizing-the-ui:

Customizing state colours
-------------------------

.. versionadded:: 1.10.11

To change the colors for TaskInstance/DagRun State in the Airflow Webserver, perform the
following steps:

1.  Add the following contents to ``airflow_local_settings.py`` file. Change the colors to whatever you
    would like.

    .. code-block:: python

      STATE_COLORS = {
          "deferred": "mediumpurple",
          "failed": "firebrick",
          "queued": "darkgray",
          "removed": "lightgrey",
          "restarting": "violet",
          "running": "#01FF70",
          "scheduled": "tan",
          "skipped": "darkorchid",
          "success": "#2ECC40",
          "up_for_reschedule": "turquoise",
          "up_for_retry": "yellow",
          "upstream_failed": "orange",
      }

    See :ref:`Configuring local settings <set-config:configuring-local-settings>` for details on how to
    configure local settings.

2.  Restart Airflow Webserver.

    See :doc:`/administration-and-deployment/modules_management` for details on how Python and Airflow manage modules.

Customizing DAG UI Header and Airflow Page Titles
-------------------------------------------------

Airflow now allows you to customize the DAG home page header and page title. This will help
distinguish between various installations of Airflow or simply amend the page text.

.. note::

    The custom title will be applied to both the page header and the page title.

To make this change, simply:

1.  Add the configuration option of ``instance_name`` under the ``[webserver]`` section inside ``airflow.cfg``:

.. code-block::

  [webserver]

  instance_name = "DevEnv"


2.  Alternatively, you can set a custom title using the environment variable:

.. code-block::

  AIRFLOW__WEBSERVER__INSTANCE_NAME = "DevEnv"

.. note::

    From version 2.3.0 you can include markup in ``instance_name`` variable for further customization. To enable, set ``instance_name_has_markup`` under the ``[webserver]`` section inside ``airflow.cfg`` to ``True``.
