    Vintage Lighting Old color puzzle/question

    I'm cleaning out my gel drawers and finding some un-identifiable color. So for you history buffs, help!1.) I know that one is a Roscolux colored diffusion of the R120 range, but in Sky Blue, that's been discontinued. (the student who wanted 2 cuts, cut off the label!! I seem to recall R128?)...
