Extreme color & flavoring

Don't know how to phrase this question;
but my wife just purcahsed a Wild Blue, Wild Blueberry beer and she absolutely loved it; which is a huge step because she normally can't even stand the smell of brewski.
THis beer is purple is color, has a strong blue berry taste, 8 abv%, and has a lot of carbination...... any idea on a recipe

or how do create such a brew using such ingrediants like Blue Berries.
How do you brew batches like this, and when do you add such ingredients.

I would blend up the berries to allow the brew to leech the color from the skins.

I presume the longer the berries are in the brew the deeper the color.

Wheat beer + 3 lbs of frozen blueberries in the secondary and 1/2L of da Vinci (with Splenda) Blueberry syrup. Tastes like Blueberry soda, which is exactly what my Lady ordered.

Looks more pinkish purple than a deep purple (I'm a Highway Star....).

How long did it take to clear, if ever?

David;
When you added the blue berries did you soak them in vodka to sterilize prior to?
This 1/2 L of Da Vinci Blueberry syrup, did you just pour that strait in while you racked into your secondary? and how much Splenda did you use with this 1/2 L?
Fermenting times? Temps?
