Abstract
A color insensitive scattering pigment is disclosed. In an embodiment, the scattering pigment is composed of particles of a range of sizes. In at least one subrange of the range of sizes, the particles are present in such relative proportions that the v/v concentration (volumetric concentration) of a particular size of particles is proportional to the size itself. In an embodiment, such a scattering pigment is included in light guides to scatter light from a primary light source.
