That's interesting but I thought the only ones that were yellow were the flight connections ones before! We always used to do a PA saying follow the yellow flight connections signs and now we say follow the Purple flight connections signs. However unlike T5 which we walk through all the time, we were very rarely in T4 or T1, so I'll have to bow to your superior knowledge.
