Saw the new floor colour Boston Dark today, we had ordered this in our new 17.56.1OB that is now an 18.58.1OB. Looks pretty good and will definitely hide the dirt better.
Sorry @Tricky this is the only other photo I got. We have actually ordered and signed off on the "charcoal" as the base and the bolster cushion of our club lounge in the 18.58.1
