Gel (lighting)

Gel lighting refers to a thin, colored filter placed over a stage or studio light to alter its color and mood. These gels are made of heat-resistant plastic or polyester and come in various hues. By using gels, lighting designers can create different atmospheres, highlight specific areas, or produce special effects without changing the actual light fixtures. They are easily positioned over the light source and can be layered for complex color effects. Gels are a versatile, cost-effective way to enhance visual storytelling and set the tone in theater, film, photography, and live events.
