The heart of Inkopolis is Inkopolis Plaza, where Booyah Base can be found. Stages in Splatoon, such as Urchin Underpass and Blackbelly Skatepark, are located around the city as well. The Inklings you find in the plaza are all players met online through Miiverse. You can see that player's Miiverse posts and order their gear through Spyke. An Inkling's hair color reflects what color they were in their last multiplayer match; it can be any of the well-known colors like Orange, Cyan, Blue, Teal, Magenta, Orange-Yellow, etc. when they leave Turf War. When the Inkling moves on to Ranked Battle, it also has the possibility of more distinguishable colors like Crimson, Minty Green, or Light Yellow. If you've just come out of an online match, inklings you played with may also show up in the plaza as well.
