What term describes the system of giving actors and other staff cues by light?

The term that accurately describes the system of giving actors and other staff cues by light is Cue Light. This system utilizes a series of colored or standard light signals to communicate specific instructions or actions during a production. For example, a green light might indicate an actor should start their entrance, while red could signal to prepare for a scene change. Cue lights enhance coordination and communication backstage, ensuring smooth transitions in performance without interrupting the flow of the show.

The other terms, while related to lighting or staging, do not specifically refer to the cue system. DLC pertains to digital content related generally to entertainment and not specifically to stage cues. Cross Fade refers to a lighting technique where one light fades out while another fades in, used for smooth transitions but not directly for providing cues. Dim Out describes a complete reduction of light, primarily used to end a scene rather than communicate cues.
