Subtractive and additive colour mixing
Subtractive - placing two different gels in front of the same lantern. Subtractive mixing is used to create a colour effect that is not available from stock or from manufacturers, although the wide range of available colours is so wide that the need for subtractive mixing is reducing. Combining colours in this way reduces the light towards blackness. The three primary colours of light (Red, Green and Blue) mix subtractively to form black (or to block all the light).

Additive - focusing two differently coloured beams of light onto the same area (eg. Cyc Floods). Combining colours in this way adds the colours together, eventually arriving at white. The three primary colours additively mix to form white, as do the complementary colours.

In a theater production, lighting technicians work under the lighting designer and master electrician. In video, television, and film productions, lighting technicians work under the direction of the cinematographer and gaffer. In live music, lighting technicians work under the chief lighting technician, who reports to the production manager.
Lighting technicians are responsible for the movement and set up of various pieces of lighting equipment for visual effects. Lighting Technicians may also lay electrical cables, wire fixtures, install color effects or image patterns, focus the lights, and assist in creating effects or programming sequences.
