We study a simple Markov chain, known as the Glauber dynamics, for generating a random k-coloring of a n-vertex graph with maximum degree 驴. We prove that the dynamics converges to a random coloring after 0(n log n) steps assuming k 驴 k_0 for some absolute constnat k_0, and either: (i) {k \mathord{\left/ {\vphantom {k \Delta }} \right. \kern-\nulldelimiterspace} \Delta } 驴* 驴 1.763 and the girth g 驴 5, or (ii) {k \mathord{\left/ {\vphantom {k \Delta }} \right. \kern-\nulldelimiterspace} \Delta } β* 驴 1.489 and the girth g 驴 6. Previous results on this problem applied when k = 驴(log n), or when k 11驴/6 for general graphs.
