The present disclosure relates to an optically colored body comprising at
least one micelle, wherein the micelle comprises a liquid medium and
colloid microcrystals having aggregates of spherical nano-particles and a
cosmetic composition comprising the optically colored body. The present
disclosure also relates to an optical structure comprising at least one
substrate, and at least one wall that covers the at least one substrate
and has optical transparency, wherein the space between the at least one
substrate and the at least one wall is filled with colloid microcrystals
having arrays of spherical nano-particles. Further, the present
disclosure relates to a cosmetic composition comprising at least one
optically colored body and/or at least one optical structure and a method
for producing the optical structure.
