"WebbThis process forms a tan-colored compound called hemichrome, which gives medium-done meat its color. When the interior of the meat reaches 170° F, hemichrome levels rise, and the myoglobin becomes metmyoglobin, which gives well-done meat its brown-gray shade. White meat is made up of muscles with fibers that are called fast-twitch. " - Slow twitch fibers color
