If that was me, burnt/blood orange would probably be the last colour I would choose, unless you want to make a really bold statement, that is personal to you?? If you are looking to co-ordinate, then an oriental rug with sage, beige and grey (grey works really well with sage) or alternatively, you know those rugs that have material like a door mat, can't think of name of it, one of these in beige, they add a young feel, (I feel) to a room. Another colour that actually works well with sage and dark brown is pink, not cerise but stronger than baby pink.
