Can anyone get post or link me to images/panels of Hush Tubes from between Justice League of America #1 (2006) & Justice League of America #4 (2006)!

Also can you tell me if it is true that Hush Tubes are Blue in colour instead of Yellow/Gold colour?
I do not own any of the comics mentioned on this page so I can not check myself!

As far as I can tell only one Fartherbox that owned and used by Doctor Impossible has ever created Hush Tubes no other Fartherbox or Motherbox has done this to my very limited knowledge!
