Kerchak is an impressive male gorilla with deep brown fur that is streaked with a striking silver-gray tuft that runs down his back. His thick arms, legs and long tail demonstrate his strength and stoutness. His eyes are a deep brown, belying the wisdom that you can find in the wrinkles of his face. Coloring him could begin with adding a creamy shade of brown to his fur. The streak of silver on his back and tail could be a pale gray and the deep brown of his eyes could be highlighted with a metallic sheen. For extra texture and dimension, use a light brown to soften his more prominent features and add a few flecks of black throughout to give it depth.
