I'm guessing this never installed Milgard picture window is less than five years old, but it was left out in the rain for a while. This model has a bronze exterior, with flush to outside of building trim flange, and white interior. There's no energy tag left on this one, but some red Milgard tag residue remains. Any blue you see in the photos is the leftovers of the tape Milgard wraps these windows to protect the exterior finish, which may now have some cosmetic damage.
