Just to add to the "pointless erudition" :-) , the Roscos Permacolor are
dichroic on glass substrate.
B&H sells them is various sizes, the smallest 2X2" or 2" round are less than 9$
each but you can have them in much bigger sizes.
Various colors are available, the classic CMY or RGB + various others.
