A multi-layered veneer for a tire sidewall is disclosed wherein one or more layers of the veneer include at least one pigment to provide a desired visual effect for the tire sidewall. In one embodiment, the multi-layered veneer includes a tie layer and a first thermoplastic layer bonded to the tie layer. The tie layer is capable of bonding the veneer to a sidewall compound of a tire sidewall. The first thermoplastic layer includes a thermoplastic material and the tie layer includes no less than about 80% by weight of a synthetic polymer chosen from EPDM, EPR, polyethylene, or combinations thereof. The synthetic polymers have a Mooney Viscosity (ML 1+4 at 125° C.) from about 5 to about 40, and the EPDM and EPR have an ethylene content of about 70% by weight to about 99% by weight of the polymer. One or more pigments are dispersed in the tie layer and/or the first thermoplastic layer so as to provide the visual effect.
