When shifting spheres, here always arose purple backgrounds. Why?
Due to the band limited character of the image small negative values might occur in the sphere. Remember that the spheres are stretched so the originally black "0-values" are stretched to some small non-zero value. When viewing the image in false colors, the background is not the lowest color and will thus appear in purple.
