The invention is related to a colorant composition used for the color layer in a colored contact lens. The colorant composition improves the adhesion of the colorant to the surface of the contact lens and provides more hydrophilicity and biocompatibility. The colorant composition for the color layer comprises at least one hydrophilic monomer, an adhesive resin, a film-forming agent and a polydopamine-modified colorant.
