Where is the config folder for JetBrains IDE?

I am trying to add a custom color theme to my phpstorm and everything I read says you need to add a colors folder inside of the config folder, and then copy the xml or icls file in there, but I can't find the config folder.

C:\Program Files\JetBrains\PhpStorm 2017.1.3

I am in the right directory but there is no folder called config and I'm not sure what to do. Could it be in some different place?

have a look at https://intellij-support.jetbrains.com/hc/en-us/articles/206544519-Directories-used-by-the-IDE-to-store-settings-caches-plugins-and-logs

you should find your config files under

c:\Users\yourname\.PhpStorm2016.1\config
