Purple Default Block

The Purple Default Block is the non-textured, default block that appears when the texture for a block has been removed or cannot be found, such as for the Locked Chest, or when the player edits the inventory or uses the /give command to spawn blocks with an incorrect data value, such as a wool block at data value 16. When placed, it will appear as white wool, but will appear as such to the player.

Properties
This block cannot be placed unless hacked into it by using programs such as MCEdit. It is unknown of its properties, or whether or not it can be used in the same recipes as wool itself.
