Whats the name of the purple berrry chips at subway?

Question

I know they recently brought that out, and i wanted to know what they were called.

Answer 1

Whatever it is, it's so new that there is nothing on the internet.  It must be something that is being "test marketed".  

All I could find was those blue potato chips called "Terra Blues".  They get their color from Peruvian Blue Potatoes.
