+    org.freedesktop.impl.portal.Settings:
+    @short_description: Settings portal backend interface
+
+    This interface provides read-only access to a small number
+    of host settings required for toolkits similar to XSettings.
+    It is not for general purpose settings.
+
+    Currently the interface provides the following keys:
+
+    * ``org.freedesktop.appearance`` ``color-scheme`` (``u``)
+
+      Indicates the system's preferred color scheme.
+      Supported values are:
+
+      - ``0``: No preference
+      - ``1``: Prefer dark appearance
+      - ``2``: Prefer light appearance
+
+      Unknown values should be treated as 0 (no preference).
+
+    * ``org.freedesktop.appearance`` ``accent-color`` (``(ddd)``)
+
+      Indicates the system's preferred accent color as a tuple of RGB values
+      in the sRGB color space, in the range [0,1].
+      Out-of-range RGB values should be treated as an unset accent color.
+
+    * ``org.freedesktop.appearance``  ``contrast`` (``u``)
+
+      Indicates the system's preferred contrast level.
+      Supported values are:
+
+      - ``0``: No preference (normal contrast)
+      - ``1``: Higher contrast
+
+      Unknown values should be treated as 0 (no preference).
+
+    Implementations can provide other keys; they are entirely
+    implementation details that are undocumented. If you are a
+    toolkit and want to use this please open an issue.
+
+    Note that the Settings portal can operate without this backend,
+    implementing it is optional.
