I hear ya. In the render I see white and brown. In reality I see blue and black, and it's the same viewed in person. I'm still hopeful this will all balance out once more is revealed.
I took a gander at FCP this past Saturday, and the new glass looked white to me. I don't know about you guys but in the second photo, I do see a bluish-toothpastey tone on the west side, but a vibrant, pearly white on the south side. Regardless, this new facade looks exceptionally sharp.
I believe in the video they have on the project website states that the windows are not being replaced. For value for money likely makes more sense to just upgrade the HVAC plant instead to gain efficiency. It isn't like the building is single pane of anything.
While I love the dark corner panels, they really change the look of the building. I think I would have stuck with the original vision of the building for historical reasons.
