My new living arrangement will be in the basement of a house my friends and I are renting. The house is kind of older, so it's going to be kind of tricky finding good newer style furniture that won't clash with the rooms. The basement has gray carpet (blah) with wooden walls that have sort of a mix of green and light brown color.
I love the idea with the navy and the orange! Very cute, modern, and classy. The walls might not match, but its worth a try. I think it will work. This may seem a little crazy, but you could get like the paint swatches at Lowe's or Home Depot of navy, orange, grey, or whatever colors you want and hold them up to the walls to see if they clash. It's worth a try.
