Anyone grow out a Dutch Passion Auto Blueberry?

If so what are your thoughts? Tips? Did it actually turn blue/lavender? Or do you have to do something to bring out the color? I have heard colder water, or is it lower room temps?

I haven't grown the Dutch Passion Blueberry but I did grow the Taiga recently and was happy with the results. Just received my latest Dutch Passion order yesterday. I got some Think Different, AutoXtreme, and Star Ryder. I was thinking about the Blueberry next time though.
