Both, in a way.  The validator uses the DTD as its source for
validation, and <!ENTITY % Color "CDATA"> allows any character
data.  Some details are also noted in the DTD, but only as a
comment for human readers.  The validator is only a program,
it cannot interpret prose in a comment.

Of course "transparent" isn't okay, but the validator cannot
know this based on an <!ENTITY % Color "CDATA">
