As the picture depics some of my folders turned grey after I executed Killall Finder command. For your information, I run a macOS 10.14.6.
Do anyone know what this means, and how to get it back to normal again?
Thank your for your time

They're hidden files & folders.
Since Sierra you can toggle visibility simply using Cmd ⌘ Shift ⇧ . [period]
Prior to Sierra you would need to toggle visibility in Terminal or by script & then kill the Finder to make the changes register.
See How to show hidden files on mac without Terminal for the scripted method.
