Day 267-Periwinkle Blue 4 Spout
Originally, I was at a loss to determine the color of this water bottle. It is not dark enough to be Cobalt or Electric and it was not cased so it cannot be Azure or Ocean Blue. I had decided to call it morning glory until I thought to compare it to another water bottle that was made in 2007 which was an experimental color called Periwinkle Blue. It was an identical match. So now I know that Periwinke Blue was made in 2007 and 2011. Any other dates out there?
