The rug is GORGEOUS...but it is blue. There is nothing charcoal about it. As you can see in my pictures, my light grey sofa, charcoal ottoman, and slate wall feature do not match my hue carpet. I am sure the lighting and my red mahogany floor dont help, but the carpet is blue. Unfortunately due to a series of events out of our control, we were not able to open the rug within the 90 day return period, so we are going to relocate it in our bedroom as that is our next room remodel - our color pallet will be inspired by the rug. As for the many comments about shedding, it is a wool rug - thats just how wool rugs work. The rug this replaced was 10 years old and was still shedding (at a lower rate, but shedding nonetheless). 
If the color was remotely in the grey family I would give this rug 5 stars as it is absolutely gorgeous, but it should be labeled as blue.
