Hi, I would have answered earlier but I never get the nice questions like this one!! I have dark furniture and have just painted my living room a Mexican orange which is a bit like a red, brown colour. I painted a feature wall that colour as I just felt it would be too much otherwise. I used a sort of very light tan on the surrounding walls. It’s called Hessian by dulux. If you like the red brown orange idea, perhaps get the colour swatches from the paint shop and in the same grouping choose the sheets and curtains (you know colours that are in that family) which would be various shades of red/orange going lighter or darker. Red sheets sound nice, with a dark beige duvet n top.
