In Cities Skylines are in main game panel three bars which has three colors > green, blue and yellow < this bars signalize you what type of zone you need to build.
These bars are in all version of game and don’t have matter on which device you play. As I said these bars show you which zones you need to build. For you this will mean:
- Green is higher than other you must build resident zones
- Blue is higher that others you must build commercial zones
- Orange is higher than others you must build industrial zones or office zones
There are some screenshots from mine latest city “las rico” when I played when I written articles for StrateGGames. I’m commenting this stages and what I do next…

After three bars which I see above I’m extended mine main route where I’m building new commercial zones and around this commercial zones I’m builded more resident zones.

So I’ve builded resident zones to boost population and after that orange column grows. So I’m must build more industrial zones…

… on examples above I’m described you how to works with demand bars in Cities Skylines and which zones you need to build. If you want to know what your citizens need after you could check it buildings details if you hover to these levels.
