The present disclosure provides an optical film, a structural colored pigment, and a method for preparing an optical film. The optical film includes a multilayer film. The multilayer film includes films with high refractive indexes and films with low refractive indexes alternately arranged in a multilayer manner, and a middle film. Some of the films with the high refractive indexes and some of the films with the low refractive indexes are disposed on a side of the middle film, constituting first other films. Optical thicknesses of films having a same refractive index in the optical films and an optical thickness of the middle film are all different or partially different.
