Both the New Orleans Square (dark purple) and Fantasyland (light purple) YAH mugs were purple on the inside. The NOS one features the Haunted Mansion and is currently available (along with the Adventureland one, which is green). They're available only in Disneyland at the Market House (on Main Street). They also have a mini-YAH mug/ornament/demitasse with the Fantasyland design.
