So, if the lighting changes the color of the costumes from scene to scene, this relationship may be difficult to be read. If costume and scenery colors are too similar, the characters may end up blending into their surroundings. Backlighting with a different color, or a light set wash, can help alleviate this problem. A set with a great amount of fine detail will go virtually unnoticed if the lighting is too dim. On the flip side, if there is not much detail, perhaps the scenic designer expects a certain location to appear dark and shadowy.
Plasticity affects the set and the performers.
Draping and translucency in costumes can be a visual success or failure with the wrong angle or intensity of light. In arena or thrust theatres, costumes are often heavily relied upon to help display a sense of time period and style. For these settings, scenic pieces can easily destroy audience sightlines. The closer the audience gets to the actors, the more detail that is needed in the costume pieces. Color variation in costumes can also be hidden in dark scenes.
