File Status Highlights
In WebStorm, each file has its own status marked with a specific color. A file status shows how the actual file's content corresponds to the one marked as 'current'.
In the editor, each line in a file is checked for its correspondence with the 'current' state and is marked with a specific color in the left gutter area.
You can customize the default colors:
For files: In the Settings/Preferences dialog (Ctrl+Alt+S), under Version Control | File Status Colors
For lines in the editor: In the Settings/Preferences dialog (Ctrl+Alt+S), under Editor | Color Scheme | VCS.
