Battleship gray
From KGB Wiki
The most marvelous color of the very first Quonset hut-shaped KGB booth "Land The Plane In Red Square" from Carnival 1989, winner of the Chairman's Choice Award (sometimes called the "Pete Berger Booby Prize"). Unfortunately it's glorious winning streak was ended when "The Hunt For Red October" finished dead last at Carnival 1991. So it was relegated to its proper use in painting and watersealing basements.
