These rugs are stunning!  The titanium rug is the dark gray one.  That picture is also shown for the silver rug, which resulted in many people commenting that the rug was lighter than they thought it would be (those who purchased silver).  I bought two 10x14 titanium rugs, and they are the dark gray as pictured.  I was concerned about vacuuming, but tried with the carpet roller going, and they vacuumed beautifully.  The pile and sheen are gorgeous.  I couldn't be more pleased.
