What is the purpose of gel in stage lighting?

The purpose of gel in stage lighting is to change the color of the light. Gels are filters made from colored materials that are placed in front of lighting fixtures. When light passes through these gels, it alters the color, allowing designers to create specific moods, enhance the visual storytelling, and add artistic elements to a production. The various colors of gels can also be used to achieve different lighting effects that complement the set design and costumes, creating a cohesive aesthetic for the performance. In essence, gels are crucial for establishing the desired atmosphere and emotional tone on stage, making them an essential tool for stage lighting design.
