The red stage has stronger visual impact and attraction in stage design. Red is a color full of energy and passion, which is often used to express strength, enthusiasm and tension. On the stage, the red background helps to create a tense and dramatic atmosphere and enhance the appeal of the actors' performances. Red also has a high popularity, which can attract the attention of the audience and make the performance more eye-catching. In contrast, although purple is also a mysterious and romantic color, its visual impact and attraction on the stage are not as strong as red. From the visual effect and stage expressive force, the red stage is better.
