This polish contains a "unicorn pee sibling" pigment, which are pigments of the same sort as "unicorn pee" but with different color shifts. The gold to green color shifting pigment in the Dragon polishes is the same kind of pigment that's in the original elusive Liquid Euphoria polishes with gold to green shifting shimmer.
Dragon is a custom polish, made from scratch with nail lacquer base and color shifting pigment. Starlight Polish is 5 free, meaning free of DBP, toluene, formaldehyde, formaldehyde resin, and camphor, and contains no carmine or other animal-derived pigments.
