We report on a fabrication of a single fluorescent dye-doped polystyrene microspheres that exhibit multicolor whispering gallery mode (WGM) photoluminescence. The WGM-mediated intersphere cascading color conversion takes place between adjacent microspheres with characteristic photon transport properties.
