Beautiful Wall Decor

I recently bought a beautiful rug for my living room - brown base with splashs of yellow, red and orange in it (almost 3Dish). It's very contemporary and I like it alot. Recently, I found some decor pillows that have the exact same design ( brown with the same colored circles, i believe the pillow designer was VERY inspired by the rug if you get my drift)...anyways, I love the pillows but I am unsure if it would be a faux pas to have them on my sofa. By the way, my sofa is a modern/contemporary neutral/light beige color so any color will pop on it. My walls are a fall green so anything green would be overkill. I was going for a fall theme when I chose my colors.
