The present invention provides a method for making colored silicone hydrogel contact lenses. The method of the invention comprises the steps of: (a) providing a contact lens constructed of a silicone hydrogel; (b) applying a color coat to at least a portion of a surface of the lens with an ink, wherein the ink comprises at least one colorant, a silicone-containing binder polymer, one or more vinylic monomers, and optionally a diluent, wherein the silicone-containing binder polymer is a copolymerization product of a polymerizable mixture including (i) at least one hydrophilic vinylic monomer; (ii) at least one functionalizing vinylic monomer; (iii) at least one silicone-containing vinylic monomer or macromer; (c) curing the ink in the presence of an adhesion promoter, thereby causing the color coat to adhere to the lens.
