A film and video correction filter that cuts green, used on lights whose white sits above the blackbody line, especially fluorescents and some LEDs. It comes in full, half, quarter and eighth strengths; plus green does the opposite, adding green to match tungsten fixtures to an existing fluorescent environment. Many LED fixtures have a built-in plus or minus green adjustment that crews call by the gel name.
Office tubes are going green on camera, sleeve them in minus green so the background matches our key.
