Purple Default Block



The Purple Default Block is the non-textured version of blocks, and is the base template for textured/existing blocks. It may appear 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. In this case, it will appear as wool when placed but will appear as the untextured block to the player while in their inventory.

Properties
This image is what blocks look like without a texture. The block data still exists for the textured block it is supposed to be.

This block cannot be placed unless hacked into it by using programs such as MCEdit, since when placed by a player it will appear as the block it was supposed to be, say if you used a data value, like wool at value 16, placing it would revert it to white.
