Minecraft wiki entry for Making_nice_floors, associated text: Glazed terracotta is great when used to highlight certain parts of a floor, specifically in a castle or royal house. What makes glazed terracotta unique from other blocks, is that different textures and colors are shown throughout the block, unlike most blocks, which are one color throughout. Lime glazed terracotta is great for a royal-looking floor, while red glazed terracotta is great for a fancy carpet. Orange-glazed terracotta is great for a beach-hut floor, or the floor for a party place.
