Modern gels are thin sheets of polycarbonate, polyester or other heat-resistant plastics, [2] placed in front of a lighting fixture in the path of the beam. Gels have a limited life, especially in saturated colors (lower light transmission) and shorter wavelength (blues). The color will fade or even melt, depending upon the energy absorption of ...
A colour scroller moves plastic "gel" colour gel [actually dyed polyester and/or other base materials coated with dyes] into the beam of the light. It is generally attached to the gel frame holder at the transmitting end of a lighting fixture, so colour is introduced after the beam characteristics have been defined by the optics of the lighting ...
Color correction is a process used in stage lighting, photography, television, cinematography, and other disciplines, which uses color gels, or filters, to alter the overall color of the light. Typically the light color is measured on a scale known as color temperature , as well as along a green – magenta axis orthogonal to the color ...
Winsor & Newton suggests the use of Liquin as a ''fat'' or ''flexible'' agent, to increase the flexibility subsequent layers. [1] While Liquin Original, [2] and Liquin Light Gel Medium [3] are mixtures of petroleum distillates, Liquin Oleopasto, [4] and Liquin Impasto [5] are mixtures of alkyd resin and petroleum distillates.

With the technology of halogen lamps improving, the 80s and early 90s saw a new breed of DJ light starting to evolve. This was a projection-style DJ light that used a halogen lamp and a mirror to reflect the light. A halogen lamp shines onto a mirror via a filter gel sheet to create the color and sometimes via a gobo wheel to create shapes. In ...
