What is the purpose of gel frames in lighting?

The purpose of gel frames in lighting is to hold color media, or gels, in place in front of a light source. Gels are thin sheets of colored plastic that modify the color of the light emitted by theatrical and stage lighting fixtures. By using these gel frames, lighting designers can easily switch out colors to achieve the desired aesthetic for a performance or to create specific moods and visual effects.

This ability to change colors is crucial for enhancing the visual presentation in stagecraft, allowing for greater creativity and expression in lighting design. The gel frame ensures that the gel remains securely in position, avoiding shifts that could lead to uneven coloring or distraction during a performance.
