In IntelliJ IDEA each file has its own status marked with a specific color. The file status denotes correspondence of the actual file content with the one marked as 'current'.
In the editor, each line in a file is checked whether it corresponds to the state at the 'current' point and marked with a specific color at the left gutter area.
You can customize the default colors:
- For files - in the File Status page of the Colors and Fonts settings.
- For the lines in the editor - in the General page of the Colors and Fonts settings.
