The present invention is a composition which can obtain color without using pigments or dyes, is a colorless composition before mixing the two-phase liquid phase, a coloration composition that can be developed after mixing, and a coloration composition capable of obtaining stable color development subsequently. It consists of a liquid separated into two phases having the point of refraction of each liquid phase in the wavelength range of 400nm to 800nm, by forming a continuous phase and a dispersed phase by mixing and dispersing the two phases A powder dispersion consisting of a chromophoric composition characterized by coloring, and a solid phase comprising a liquid phase and a silica powder, wherein the liquid phase has a refractive index of n1 and the silica has a refractive index of n2, which is represented by the following formula (1): The coloring composition characterized by coloring by the difference in the refractive index at the interface between the liquid and solid phase by satisfying, It is characterized by the cosmetics used, fragrance products, and sundries used as display products.n n n (Equation 1) |
