Here is a color chart of soft glass colors.  Currently, I have pictures from 4 different manufacturers.  Here you will find mostly Italian glass, Effetre - with some Vetrofond mixed in - Czech Glass, from Czechoslovakia,  and Lauscha, from Germany.  (Bullseye will come soon, but it will take some time to get it all done.)
