Overview

The Rosco Roscolux #368 Winkler Blue gel filter is a specialized color media designed for professional lighting applications where a cool, silvery-blue tone is needed. Named after its distinctive hue, the Winkler Blue has earned its place as a preferred choice among lighting designers for creating realistic moonlight washes and atmospheric front-light effects on stage, in film, and across event productions. The 20" x 24" sheet size is the standard professional format, offering flexibility to cut pieces for a wide range of fixture types and frame sizes.

With a light transmission rate of 16%, this gel absorbs a substantial portion of the light passing through it, which is essential to achieving that deep, convincing blue tone. This means your source fixtures need adequate output to deliver the desired intensity on stage or set. As part of the Roscolux line, this filter is manufactured to meet the demands of professional environments, offering reliable color consistency and reasonable durability under the heat of stage lighting instruments. Whether you are designing a night scene for a theatrical production or adding cool-toned depth to a concert stage, the #368 Winkler Blue delivers a refined, elegant result.
