Most German color is a 24 % lead base with the exception of the bright red and yellow glasses which are lead free. Lead makes cadmium yellow turn an ugly brown. If there are other colors that are lead free, I'm not aware of them, beyond my own. Lead tends to make Linear expansion issues more forgiving when mismatch occurs.

It would not be all that hard to make some colors using cullet of your own. It's limiting certainly. Spruce Pine color base or regular will make a fair number of colors.
