The 16mm films I am aware of that are orthochromatic are:

    7302 BW print -- use a yellow or red safelight
    7363 BW High Con (what Madison is referring to) red or yellow
    7373 BW Sound Recording film (Now 7378?) red, NOT yellow

I am not aware of any orthochromatic color films -- it seems like an
oxymoron, a color film that does not respond to all colors, but why not --
does anyone know of one?
