red branches from cold weather

A couple of weeks an arctic blast started making it's way to the deep south & my girl who was only 2 weeks old at the time was affected by the cold weather. The main stalk started to turn red as well as branches. The weather started warming up a couple of days ago & the new growth is doing great. She's starting to grow normally again. My question is this. Will the red branches turn green again ?

Thanks, Mookie
