The files are displayed in color. After I ran 'chmod -R 744 /boot' the colors disappeared after running the same command:

Why did this happen? The permissions haven't even changed, right? When logging in as another user (non-root) and typing 'ls -la /boot/' it will show up in color. Why is this happening and how to get the colors back for root?
I wanted to change the permissions for the files in /boot but they seem to have had the desired properties to begin with, so I don't get why the colors disappeared.
