I only want the silhouette of a person in a studio recording and another one dancing, a girl dancing, but only put her silhouette and a studio in light blue . So that you understand more or less what I want is that on a black wall and in a dark room where everything is dark, a person has been illuminated by a blue light while he is recording and another one is dancing, but those people are not going to be seen, a silhouette is going to be seen and the outline is going to be the blue light and they are going to be inside a dark room.
