Silk would be interesting, not to mention elegant. As for paints, the Silver Illusion appeals, but it might throw green (not sure). I also agree the Tranquil Retreat is a good one. I'm wondering how big the feature wall is, and what is going on this wall, eg TV, fireplace, large artwork, etc.?

What natural light do you get in the room/what orientation? i.e. is it a 'cold' or 'warm' room? If it's a colder room, I'd go with a grey with orange/red undertones to warm it up a bit, or if it's a warm room you could get away with a cooler grey, maybe green undertones to compliment the maroon. Or you could even try a green rather than grey. The Aerobus is a blueish grey so will be cooler. As others have said you would probably want a lighter tone than this for the walls (unless you're purposely going for a dark dramatic mood). 'Miller Mood' is a couple of shades up in the Colour Atlas. Get sample pots and paint a section on each wall, or paint a white bit of card and stick to the wall to see how the light is at different times of day.

What colou did you go with? ImI'm having the exact same problem

Hi Kieren, a rich, cool sand colour might work. Avoid yellow undertones. I think you’re right to stay away from anything too dark. Or try a pale beige textured rug. Added bonus, it’d be easy to find. A rug that mixes something similar to your couches with a LITTLE bit of green and maybe a bit of blue could also look nice. Accent the room in mid blue too, maybe? Stay in proportion to the room, but go bigger rather than smaller with the rug. Rug retailers will usually lend you a rug so you can try before you buy, which can be useful and some will bring samples to your door. Good luck
