An enzymatic polymerization method of covalently linking a colorant to a polyester to produce a colorant-polyester compound, the method including the steps of: (a) providing a reaction solution comprised of an ester monomer, a colorant having or functionalized to have a hydroxyl group, and an enzymatic catalyst; (b) reacting the ester monomer and the colorant using the enzymatic catalyst to produce a polymeric product, wherein the polymeric product includes a colorant-polyester compound; and (c) separating the polymeric product from the reaction solution. A colorant-polyester compound includes a colorant covalently linked to a polyester and the polyester is obtained by polymerizing a lactone.
