With this simple drawing we put into practice the value, the theory of the shadows, and the representation of space in classes of seventh grade. The tubes are drawn with a ruler on the drawing pad. We have superimposed 4 levels of pipes, some with connecting joints on the corners. After drawing the lines with a black marker, we have colored the pipes with oil pastels, imagining a light source coming from the left. In this way on every pipe we created a value scale shaded with gradations of various colors.
The oil pastels allow the blending of one color into another and the chiaroscuro effect is very realistic. Finally we painted white space background with black tempera, to bring out the brilliance of the colors and the three dimensional effect of the shapes.
