Background color leans a little purple which I wasn't expecting. The grey background color is made from blue and purple and cream colored threads.
I ordered 2 runners for a hallway and the colors are different on each as are the grid patterns.  One rug is slightly cooler in color with wider window pattern, the other slightly browner color with a ragged and narrower window pattern.  I have ordered a 3rd rug in hopes that the new one will match one of these and return the remaining.
Otherwise these are nice rugs with a decent cushion (I have only a thin non-slip pad beneath) and feel nice under foot.
