'color palettes' to control what colors people choose to paint their facades. I mean, as long as they're not painting brick, who cares? Paint can be changed, unlike some other alterations that people do to historic buildings. And a dash of color can add drama and interest to an otherwise staid and sober downtown.
1896 doesn't make this the oldest building in Philly by any stretch of the imagination, but it's still pretty doggone old. Philadelphia has some great neighborhoods just to wander in and enjoy.
