Deep blue more saturated than Roscolux 385. Good for dark night skies or for a backlight color. A great color for rock and roll concert lighting. (Trans.= 56%).
Rosco's premier range of filters, Roscolux, is manufactured in a unique technology to insure the longest possible life under hot theatrical lights. Three discrete layers are combined in a tri-extrusion process. By sealing the colored layer between two microscopically thin layers of clear film, dye migration is minimized and effective life is extended. Roscolux (sold under the trade name "Supergel" overseas) is currently the most widely used filter range in the world.
