I want color

[Bright]

I got a Blueberry Mango Auto in a promo. It’s growing nicely and getting ready to flower. I want to put it outside to make the blue come out. My questions are how long does it need to be outside, what are the temps it can deal with? Obviously I don’t want to hurt her. I’m in Kentucky so temps aren’t extreme.
Thanks ahead of time.

Sometimes 70°F are enough to bring out leaf colours but anything under 60°F will stunt and damage your plant.
