You are of course right! I have a brown, not a blue! Not sure why I was thinking about it in reverse - oops.
Well, mine is quieter than other keyboards I've used, eg a Dell keyboard as long as you don't bottom the keys out, though I do get the occasional loudish click when the keys snap back, usually from the space bar, though if I slow down when typing I can make it almost completely silent (obviously thats not normal typing though).
 I did have a Saitek eclipse a few years ago that was quieter.
