The smoke Persian is one of the most striking patterns of the Persian colors. There are six separate colors, black, blue, cream, cameo (red), smoke tortoiseshell and blue-cream smoke. In repose, the smoke appears to be a solid color cat. In motion, the coat will break open, giving glimpses of a startling white undercoat. All should have the characteristic white ruff and ear tufts. The perfect balance of undercoat to overcoat is transitory and the perfection of color balance can usually only be seen six to eight weeks annually.
