+Deprecated RGB Formats
+======================
+
 Formats defined in :ref:`pixfmt-rgb-deprecated` are deprecated and
 must not be used by new drivers. They are documented here for reference.
 The meaning of their alpha bits ``(a)`` are ill-defined and interpreted as in
 either the corresponding ARGB or XRGB format, depending on the driver.
