Same reason why the exterior painting had stopped but has now started back up again; should be all blue-for-gold soon.
And for anyone who is still nostalgic for the gold trim: I was at the Mabee Center today and got to see the new blue panels right next to the old gold ones, and the difference is startling. The gold is so tarnished; the navy looks incredible instead. It looks like a new building.
And, while I didn’t get a chance to see it, I was told something along the lines of “If you think the exterior looks good, just wait tilL you see the renovated concourse”.
