this is a good quality maker and the colors would be subtle with a nice bold graphic to add some interest
this could be a good alternative to the striped stool, as it coordinates with the couch. I picture two of these going underneath a front hall table. It would provide you with a place to put on your shoes and have some extra seating to pull over to wherever if you ended up with a large group at your place.
if you're looking for a neutral rug (one that fits in with the gray sofa without adding a new color to the pallet) I think this is a good option. It is interesting enough to be fresh, but has the tile shapes which feel somewhat familiar to me. The pattern also seems like there are enough variations throughout it that it could cover some stains or discoloration from wear and tear.
moroccan style rugs are all over design magazines right now-- and for good reason. Their simplistic, minimal design makes them modern, but they've been used FOREVER! So-- it's both trendy and traditional. A downside to this rug is you'll have to enforce a no shoe policy or suffer the consequences.
geometric prints feel modern and playful without having to really commit to a style-specific print (like florals or fans or birds)
another good option... not as much of a pop of color, but definitely colorful and interesting
I like spending as little on rugs as possible so I don't have to freak out when people wear their shoes in the house. This is a good, inexpensive option and provides you all with the pop of color you were looking for, without having to commit to that color with a big ticket item (notice you get 75% off the listed price)
bold graphic/additional seating
perfect small scale sectional
artwork like this but to a different scale would be pretty in your space... something to tie all the colors together without drawing too much attention
