Purple Default Block

The Purple Error Block is a block that appears when a player uses inventory hacks or the /give command to try and get 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 it's properties, or whether or not it can be used in the same recipes as wool itself.
