E-Colour is Rosco's comprehensive system of European color filters for film and video production. E-Colour includes different filters and materials for color correction, color effects, diffusion and reflection. They're manufactured with the latest dye formulations and bonding technology to assure the highest levels of reliability and performance.
Because both the Rosco E-Colour and the LEE gel lines use the European gel numbering system, E-Colour #281: 3/4 CTB is equivalent to LEE #281.
