Pasting a color from DrawGraphicsPalette

Look at this simple example:

In:=Show[Graphics[{Green, Rectangle[{0,0}{1,1}]}]];

If I enter "Green" with the keyboard, I get a green rectangle as
expected. But when I paste "Green" in by klicking on the apropriate
button in the DrawGraphicsPalette (from Package DrawGraphics by David
Park) the following error is reported:

MakeExpression::"boxfmt":"\!\(TextForm\) in \!\(MakeExpression[\(\(\"Green\", \
TextForm\)\)]\) is not a box formatting type. A box formatting type is any \
member of $BoxForms. \!\(\*ButtonBox[\"Mehr\[Ellipsis]\", \
ButtonStyle->\"RefGuideLinkText\", ButtonFrame->None, \
ButtonData:>\"General::boxfmt\"]\)"

So I tried to add "TextForm" to "$BoxForms" using:

AppendTo[$BoxForms, TextForm]

Now I get a green Rectangle but still an error:

ParentForm::"deflt":"The ParentForm of \!\(ParentForm[TextForm]\) is not \
defined on $BoxForms. \!\( \*ButtonBox[\(Mehr\[Ellipsis]\), \
ButtonData:>\"ParentForm::deflt\", ButtonStyle->\"RefGuideLinkText\", \
ButtonFrame->\"None\"]\)

So I tried to define a ParentForm, eg:

ParentForm[TextForm]^=StandardForm

Mathematica doesn't like this, because TextForm is protected.

No I could unprotect TextForm an assign the ParentForm. Now all works
well, but I'm not sure if there are unwanted side-effects coming up.

Does anyone know more about this?
