The text below the diagram explains that the blue axis runs downward from the base of the ochre cube as it stands originally. The colors used include white, light yellow, green, blue, null, light blue, ochre, orange, brown, red, pink, light purple, and light green. The diagram is labeled 'Fig. 106'.
