I too love beige and blue. I’m not a pro so for what it’s worth, I used a Kayleen rug, Agora, in denim blue, I found a photo of it on shop.carpet.com although that’s not where I purchased. Our walls are a light milk chocolate color and the little bit of brownish in the rug looks good with our new wood floors, the ivory sofa, and blue collected pottery. Sorry I do not have a photo. I love the way all my colors are underfoot and enliven the room. Of course, I have many years on you so I knew what I wanted when I began looking.
