A stable, highly unsaturated hydroxy peroxide was synthesized by reacting a common food color carotenoid with FeCl 3 in air. The obtained pale‐yellow carotenoid hydroxy peroxide is easily converted into a blue, cationic polyene – then changes back to the yellow compound, showing the same characteristically dichromic properties like polycyclic, aromatic leuco dyes.
