The present invention provides a novel method for producing a filler-containing colored thermoplastic resin composition superior in pigment dispersibility and impact resistance. This method includes melt kneading firstly at least a part of components of resin consisting of a thermoplastic resin (A) and/or a thermoplastic resin composition (B) with fillers (C), adding remainder of the resin, if any, with a pigment (E), and then further carrying out continuous melt-kneading.
