Claim:
1. A method of manipulating a color displayed by a transfer medium or substrate comprising iron oxide colloidal nanocrystals arranged within chains, wherein each chain of nanocrystals is encapsulated, and wherein the transfer medium or substrate is applied to an article of footwear or apparel, the method comprising: (a) applying a magnetic field to the transfer medium or substrate to control the color displayed by the transfer medium or substrate; and (b) applying energy to at least some of the chains of nanocrystals at a level that destroys the encapsulation surrounding the chains of nanocrystals to which the energy is applied such that the nanocrystals are unable to adjust position within the chains of nanocrystals and within the transfer medium or substrate when the magnetic field is applied.
