Abstract
For at least some layers of a number of stacked layers of an optical disc that correspond to different colors, an optical beam is selectively impinged on a region of the optical disc. The optical beam has a wavelength to which the layer is uniquely sensitive as compared to other of the layers, to sufficiently heat the layer so as to cause the region to change from at least substantially translucent to a color to which the layer corresponds.
