A colorant composition capable of giving a coating film excellent in heat resistance and weather resistance which not only can have a single clear color, such as, blue, green, yellow, or the like, and be used for forgery prevention based on discrimination by means other than visible light rays, but also does not suffer color fading even at a high temperature of 350° C. to 600° C. The colorant composition comprises at least a powder comprising a base particle coated with a multilayered film comprising layers differing from each other in refractive index to make the base particle have an interference color, wherein the powder is dispersed in a dispersion medium.
