~~~~~~~~~~~~~
* Similar to the change in version 1.9 which normalized conversions to named
colors for ``gray``/``grey`` to always use the ``gray`` variant, the other
named grays of CSS3 now normalize to the ``gray`` spelling. This affects the
following colors: ``darkgray``/``darkgrey``,
``darkslategray``/``darkslategrey``, ``dimgray``/``dimgrey``,
``lightgray``/``lightgrey``, ``lightslategray``/``lightslategrey``,
``slategray``/``slategrey``.
