It is an object of the present disclosure to provide an agent for coloring keratinous material, in particular human hair, comprising (a1) at least one amino-functionalized silicone polymer, and (a2) at least pigment,
the weight ratio of all the pigments (a2) contained in the composition to all the amino-functionalized silicone polymers (a1) contained in the composition, i.e., the weight ratio (a2)/(a1), being not more than 0.95.

A second subject matter is a method for dyeing keratin material, wherein the agent is applied to the keratin material.

A multi-chrome cosmetic hair composition is disclosed. The composition includes a base formula suitable for hair and an interference pigment providing a colored background exhibiting interference colors that are observable at different angles of observation. The formula is sufficient to enable a homogenous suspension of the interference pigment. The formula includes a propellant, denatured alcohol, neutralized octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer 4, a neutralizing agent sufficient to neutralize the octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer 4 to a range of 80% to 100%, and a plasticizer. The interference pigment includes an opaque-type interference pigment consisting of particles ranging from 5 microns to 60 microns in size to fill in gaps on hair shaft surfaces and create a smooth, chrome-like effect on the hair. The interference pigment includes an inorganic layer that specularly reflects incident light and semi-transparent inorganic layers that refract the reflected light such that the interference colors are observable.
