Yep, it is nice, but I too like some ‘pop’ to a room, with bold colors.
It is elegant but rather drab IMO.
My living room is primarily black and brown but I have a large persian area rug in deep maroon with a creme sculpted border that has subtle hints of blue, green, lavender and yellow. I also have a large, 5×5 abstract painting with varying shades of teals, browns and golds.
The effect is really nice and I especially love the way the colors show up at night with the lighting.
Remeber to view the rug in both natural light and artificial.
