Claim:
1. A photonic assembly, comprising: a liquid droplet, dispersed in a carrier liquid, said liquid droplet comprising a plurality of colloidal particles, each colloidal particle comprising a light-scattering core surrounded by a first shell layer, wherein the plurality of colloidal particles is arranged with short-range order within the liquid droplet, wherein each of the colloidal particles has short-range order with up to a fifth neighbor colloidal particle, the plurality of colloidal particles being arranged without long-range order, wherein the plurality of colloidal particles is packed into the liquid droplet such that there is no observable Brownian motion in the liquid state, and wherein an observed color of the photonic assembly upon incidence of ambient light is determined at least in part by the short-range order and is independent of an angle from which the photonic assembly is viewed.
