The values in the enums above are taken from the spec.
In any case this code is still marked as "unofficial", even though all
the elements are already listed in the spec page and git repo.
Could someone more familiar with the current standardization process
chime in to confirm if these Colour elements are finalized or not? The
unofficial compliance check could be removed if so.
