The application discloses a colorful optical film, and a preparation method and an application structure thereof. Since the pitches of cholesteric liquid crystal layers in the colorful optical film can be adjusted, the reflection wavelength of the cholesteric liquid crystal layers can be adjusted accordingly to achieve different color effects. In addition, when the second coating in the coating group is in a laminated structure of multiple cholesteric liquid crystal layers, the reflection spectrum can be broadened by superposing the multiple cholesteric liquid crystal layers having different pitches. Because the optical rotation of the cholesteric liquid crystal layers can be adjusted, the colorful optical film has a high reflectance and thus a stronger metallic luster.
