I screamed when I opened the box. This couch looks so much better in person than on the photo. I got the color Moto Stucco. I have beige curtains and light natural wooden floors. My couch looks more beige than grey. 
I would imagine that if your home has grey walls , the couch would look more grey as light will reflect off the grey walls and onto the couch. 
This couch has really deep seats and the cushions has some feather fill which makes it very luxurious and soft. It feels great and I’m super happy so far
