Raycol Explained

Raycol was a two-color additive film color process developed by the chemist Anton Bernardi in 1929.^[1] It was used by Maurice Elvey to film The School for Scandal,^[2] but was commercially unsuccessful.

It used frames shot through red and blueish-green filters, which were recorded on standard black-and-white film stock, and projected with red and white light respectively.^[3]

It was covered by British patents 329,438 and 335,038.^[4]
