The invention discloses a colored polymer conductive bead and a preparation method thereof. The preparation method comprises: 1) preparation of conductive polymer seed liquid; 2) confinement and controllable swelling pretreatment of polymer beads; 3) synthesis of colored polymer conductive beads. The present invention can realize the limited and controllable swelling of the surface layer of the polymer beads through the pretreatment process of the limited and controllable swelling of the polymer beads, and then control the synthesis process factors of the colored polymer conductive beads to obtain a series of different Conductive properties and colored conductive polymer beads in different colors. The conductive polymer has good compatibility with the polymer beads, and the lower content of the conductive polymer can endow the polymer beads with better conductive effect and color without destroying the internal structure of the polymer beads. The polymer beads still maintain the foaming properties of the polymer beads.
