Answer: These trees (Pinus flexilis) should be an evergreen blue-green type of color all winter and it should also be able to withstand cold winter weather without any problem. Unfortunately, certainly the browning would be a sign of distress and could possibly indicate it is dead. I would suggest you consult with the supplier right away and see if they have any suggestions -- and if there was a warranty of any kind on the tree. They would probably like to see some photos of the overall plant as well as closeups of the browning to help them in determining what has happened. I'm really sorry I can't be more encouraging.
