Minecraft wiki entry for Pixel_art, associated text: The basic layout of the iron golem is white with "rusted" parts that are more brown. For the white or light gray parts of the iron golem, use white wool/concrete and light gray wool/concrete. For the slightly "rusted" parts, use white terracotta, light gray terracotta, and gray terracotta. White and gray terracotta are actually slightly browned, making them perfect for this circumstance. Use red and black wool/concrete for the iron golem's eyes.
