The latest campaign by Diet Coke is unique designer labels with over 2 million different designs. The campaign was created by Coca-Coca Israel with assistance from with help from Gefen Team, Q Digital and HP Indigo to auto-generate unique designs using an algorithm.
In our area (Fort Wayne, Indiana) I have mostly seen ones with white and pastels with bits of black like on the bottle above and on the plastic bottles below.
