English: Direct recomposition of the colors. "Fig. 10 shows how a common iron top, such as may be found in any toy-store, may be transmuted into a color-top. The shape of the handle is of no importance. By fastening disks of various colors, made of drawing-paper, around it, all sorts of chromatic changes may be studied. With red, green, and violet, white will appear by spinning the top. With one-quarter green and three-quarters red a deep orange may be produced. Directions are given for using the top on the lantern, and casting the colors on the screen, so that a great many persons may see it at once." |
