The at least one electrophoretic particle includes a shell and a core located within the shell, wherein the core includes a colorant and a fluorescent compound. An electric field may be applied adjacently to the fluid of the ink, and the at least one set of colored particles having the core-shell structure is movable within the fluid of the ink by the electric field.
