I can't remember what is happing for club seats or other tiers of seating. I'd kind of expect the seat colour to correspond to that, at least in the lower bowl. All black seating would be cool though!
I would prefer all black seats. Clean and classy looking. Plus it hides empty seats better than red would. I would assume red seats would appear dirty after a while.
They'll likely have 4 or more variants of seating in the building depending on how much you open your wallet.
-The regular seating in the lower bowl, likely with a cup holder
-The plush cub seats
-The even more plush suite seats
-The plain jane upper bowl seats, likely without a cup holder
etc.
And if it's like how things were done in Edmonton and Detroit the upper bowl seats will be narrow
SAP Center in San Jose has a striped pattern for their seats, thought that looked kinda cool. Looking at pictures it's 5 rows of black, 3 of grey / silver, 5 black...
