Claim 0:
1. A method for providing a selectively colorable system that produces electrical energy for charging an electrical power storage device in an electrically powered vehicle in the presence of light, comprising:
arranging an energy harvesting element on a surface of a vehicle body; and
forming an energy transmissive layer over the energy harvesting element on the surface of the vehicle body;
the energy transmissive layer having a body-facing side facing the surface of the vehicle body, and an energy-incident side opposite the body-facing side, the energy-incident side presenting a consistent opaque appearance when viewed from any aspect, and the energy transmissive layer passing 50% or more of light energy impinging on the energy transmissive layer through the energy transmissive layer to activate the energy harvesting element, and
the energy transmissive layer being formed of a material composition comprising a plurality of substantially-transparent particles and a substantially-transparent matrix material that fixes the plurality of substantially-transparent particles in a layer arrangement;

forming each of the plurality of substantially-transparent particles of
a spherical particle formed of a first transparent dielectric material, the spherical particle 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; and
an outer coating comprised of another transparent dielectric material having a selected index of refraction of 2 or less, the outer coating having a thickness that substantially eliminates reflective interference between the colors reflected by adjacent particles when in contact with one another; and

connecting an electrical output of said energy harvesting element to an electrical power storage device in the vehicle.
