I ordered the biggest size offered for my living area.  It is beautiful....not too dark due to the ivory and touch of blue that is mixed in.  The charcoal color seems more like a brown to me....maybe in between charcoal and brown.  It layed down perfectly the first day.  Definitely recommend purchasing the rug pad with it.  The rug itself is thin and the pad adds thickness, comfort and keeping it from sliding on the floor.  I am very well please with this rug!!!
