Abstract
Systems and methods of manipulating a color displayed by an article of wear comprising iron oxide colloidal nanocrystals arranged within chains are described. Steps may include forming the article of wear from a raw material that include the chains of nanocrystals, applying a magnetic field to the raw material, applying energy to at least some of the chains of nanocrystals to soften materials within the raw material immediately surrounding the chains of nanocrystals to which the energy is applied, adjusting a strength of the magnetic field to control the color displayed by the raw material, removing the energy to allow the materials within the raw material immediately surrounding the chains of nanocrystals to harden and fix a location of the nanocrystals within the chains, and removing the magnetic field.
