1. A method for making an aerosol-deliverable material composition, comprising:
providing a substantially transparent liquid binder material; and
suspending a plurality of multi-layered transparent particles in the liquid binder material, each of the plurality of multi-layered transparent particles comprising:
a spherical core comprised of a first transparent dielectric material, the spherical core having a value of a physical diameter equal to a half wavelength of a first selected color of light component to be reflected by the particle modified by a refractive index of the first transparent dielectric material;
a plurality of material layers formed on the spherical core, each of the plurality of material layers comprising at least a second transparent dielectric material, and having a value of a physical thickness equal to a quarter wavelength of at least a second selected color of light component to be reflected by the particle modified by a refractive index of the at least the second transparent dielectric material; and
an applied outer coating comprised of another transparent dielectric material, the outer coating having a thickness, and the quantity of multi-layered transparent particles being of sufficient number, that provides a desired interstitial spacing of particles so as to substantially eliminate reflective interference between the colors of light reflected by the particles.
