Snack time is fun time!

The makers of Lego Fun Snacks would like to remind you that:

Grape + Cherry = Graperry.

These are the most frustrating fruit snacks I've ever eaten. They list 4 flavors on the box. Strawberry, Grape, Orange, and Cherry. However, inside the packages there are 6 colors! And some of them don't really seem to make any sense.

Red: Cherry
Orange: Orange
Yellow: ??
Green: Strawberry (for unknown reasons)
Blue: ??
Purple: Grape

I've assumed yellow to be some kind of lemon flavor, but what the fuck is blue?

Somebody tell me!
