It is a true dove grey colour that works very well with pure white and carrera marble.  The quality is good.  Thick paper and no printing flaws.  Being a geometric pattern means pattern matching is very easy.  Only warning:  use it is a ‘square’ room ( not on wonky walls) and use a plumb line to start your first piece.  I also used a spray bottle of water to make the paper more pliable in the corners.
