+
+Superset Custom Production Config Settings
+******************************************
+
+To add or override production config settings in Superset, you can use the patch 
+`superset-config-docker`. For example, to disable any custom color schemes:
+
+.. code-block::
+
+    FEATURE_FLAGS = {
+        "EXTRA_CATEGORICAL_COLOR_SCHEMES": False
+    }
+
+Or to add a new custom color scheme:
+
+.. code-block::
+
+    EXTRA_CATEGORICAL_COLOR_SCHEMES.append(
+        {
+            "id": 'your_new_palette',
+            "description": 'Custom color scheme for Company',
+            "label": 'Custom Colors',
+            "colors": ['#11406A', '#F4661F']
+        },
+    )
+
+These changes will take effect on restart. To override *local* config settings, use `superset-config` patch instead.
