Color Gel Sheets, also known as filters, are thin, transparent sheets placed in front of stage or studio lights to change the color of the emitted light. Made from heat-resistant polyester or polycarbonate, these gels come in a wide variety of colors and are commonly used in theatrical, film, and event lighting to create mood, highlight scenes, or evoke specific atmospheres. By filtering white light into different hues, color gels allow lighting designers to achieve dynamic visual effects and enhance the overall aesthetic of a production. They are essential tools for adding creative color control to any lighting setup
