So I have an interesting question. Recently purchased a foreclosed home in a cold-weather environment.

This is probably due to the corrosion of copper pipes. If the water has not flowed for a long time and your pipes are made of copper it is probable the cause. Let the water run for a while and check the color of the water again.
If I had to take a guess at this, I’d probably say that this is due to copper contamination. A lot of homes use copper pipes for the plumbing. Since you say the house was winterized, then the water has been shut off for who knows how long. With the water turned on, it can pull copper from those pipes and turn the water a blueish tint. If this is the case, just keep flushing the system and it should resolve on its own. But make sure you have your water tested before drinking it. Good luck with the new home!
I've had the same problem, I ran the water till it gets the normal "color" through all the taps in the house, after I took samples and test them at the lab, everything turns to be ok after that. The problem of the bleu water it was the copper lines and water not circulated through for 3 months.
