How do you arrange the light for this kind of portrait photography? Red blue light and shadow on background and body

You will know the effect at a glance, using the corresponding colored projector lamp.

The one above uses a blue curtain, with white light shining behind it. Then there is a spotlight on the left and right sides of the camera, with a red cover added to shine a red light on the model, and another white light flash on top of the model flashes downward simultaneously (as evidenced by the shadow on the model's neck). The camera uses a higher shutter speed, which should be no less than 1/800th of a second. Before the shoot, the photographer had an assistant sprinkle some shredded paper foam on top of the model. In this way, this effect is formed.

In the photo below, the model is leaning against a solid white wall. A projector lamp with a red cover is placed on the left and right of the camera. The camera uses a large aperture and slow shutter speed to shoot, using a triangle. shelf.
