PROBLEM TO BE SOLVED: To provide a method for producing a colored polyurethane elastomer fiber, capable of effectively producing a small lot of the fiber with which various kinds of pigments are mixed as additives. SOLUTION: This method for producing the colored polyurethane elastomer fiber comprises continuously and quantitatively feeding a reactor for the polyurethane elastomer fiber with a raw material for the polyurethane elastomer together with slurry containing one of the pigments and a dispersion medium, uniformly stirring the raw material for the polyurethane elastomer and the slurry to form a pigment-containing polyurethane elastomer, and melt-spinning the pigment-containing polyurethane elastomer without solidifying the elastomer.
