  We study the chromatic polynomial P_G(q) for m \times n triangular-lattice
strips of widths m <= 12_P, 9_F (with periodic or free transverse boundary
conditions, respectively) and arbitrary lengths n (with free longitudinal
boundary conditions). The chromatic polynomial gives the zero-temperature limit
of the partition function for the q-state Potts antiferromagnet. We compute the
transfer matrix for such strips in the Fortuin--Kasteleyn representation and
obtain the corresponding accumulation sets of chromatic zeros in the complex
q-plane in the limit n\to\infty. We recompute the limiting curve obtained by
Baxter in the thermodynamic limit m,n\to\infty and find new interesting
features with possible physical consequences. Finally, we analyze the isolated
limiting points and their relation with the Beraha numbers.
