Also, former greatland stores (non-superT stores with two entrances) have blue doors and green doors. Greenworld is pharmacy, food ave, hba, ppc, market, pfresh, seasonal and domestics. Blueworld is guest service, photo, see spot save, electronics/mmb, stat, sport, office, small app, home decor, furniture, toys and automotive. This might vary on a store-to-store basis, but generally you'll have 1 HLTL in blue and 1 in green, as well as your CTL supporting the pfresh/market side of green.
We were a P01 store, renovated in 2007/2008. All walls are now red, except for the entrances with still keep the green/blue paint.
