What does a wash light do?

A wash light is designed to provide an even and diffused illumination over a large area, such as a stage. When utilized, it blankets the entire stage with light, often in a single color, which helps to create a uniform atmosphere. This kind of lighting is crucial for providing overall visibility and setting the mood for a performance, as it illuminates all performers and set pieces without creating harsh shadows.

In contrast, other types of lighting serve different purposes. Some lights are intended for creating specific imagery or projections, while others might focus on highlighting particular areas or elements within a scene. A wash light's primary role is to ensure that the audience can see the entire stage beautifully and uniformly, making option B the most accurate description of its function.
