A completed sphere may be dissected in any number of ways. Depending on the angle and depth of the cut different color spectrums will be revealed.
Step 4: Greyscale
Cut and mix small chunks of white, grey and black to create a grey scale. Greyscale is the vertical axis of the color sphere. Note the size of the chunks and the length of the scale. The vertical axis represents the diameter of the final product. If the chunks are too large there may not be enough material to complete the project.
