For Cubase 5.1
Green, Yellow at (more or less) -18dBfs and Red at 0dBfs, and it’s easy to tweak it. Hope it works with newer versions…
To install, copy the xml files into :
Windows : C:\Users\YOU\AppData\Roaming\Steinberg\Cubase\Presets\Configurations\
Mac : /Users/YOU/Library/Preferences/Cubase/Presets/Configurations/
(Folders may be named differently depending on your OS and/or Cubase version)
Then, in Cubase, go to preferences, load the preset you want and restart Cubase
