Let us now consider the kind of lighting which may be used in the several kinds of marionette stages. The Punch and Judy stage requires no lighting when used in daylight. But even this stage requires some thought for its lighting when it is used in a darkened room. Your set of Christmas-tree lights may be fastened to the top of the proscenium arch and an extension light may be used in the same way as is shown in the illustration. Christmas-tree lights and extension lights are all that are necessary for the table stage and the soap-box stage. In the chapter on “Making Your Stage” you will see how these lights are placed. If you have made the semi-professional stage with overhead lights, footlights, and strips, you are ready to experiment with your lighting. Begin by asking yourself whether the scenes of your play take place indoors or out of doors. What is the time of day and the season of the year? Is it an out-of-door scene, representing the cold of winter, or the heat of summer? Does your scene occur in the soft light of early morning or in the glow of sunset? Is your scene laid in a deep cool wood or in a warm sunny garden? All of these questions must be considered. Now, how can you produce these varied effects of sunlight and moonlight, coldness and warmth, somberness and gaiety? Certain colors such as red, orange, and yellow are called warm colors, because they give the feeling of warmth. Other colors such as green, blue, and violet are called cool, because they give the feeling of coolness. If your scene suggests warmth, whether indoors or out of doors, begin experimenting with warm lights, ambers, reds, and yellows. You will find that usually a certain number of white lights are needed with the colored lights in order to produce the effects you seek. [Illustration: _Marionette Ballet, "Petroushka"_ ] Everyone knows that color produces varied emotions. We are familiar with the effects of red which are stimulating, exciting, or irritating. The toreador, recognizing this principle, waves a flaming red mantle before the bull. Blue has an exactly opposite effect. It quiets and soothes, and when it runs into violet, it becomes depressing. Experiment with purple lights and you will find that they give a note of gloom, mystery, or of impending disaster. Yellow is the color that brings gaiety and light-heartedness, as you will recall when you contrast your own feelings on a sunshiny day and on a gray day.
