Dulux Quarter White Duck is a very harmonious colour as a backdrop for antiques, timber tones and strong coloured upholstery. I haven't got a reliable photo of it, but you can pick up a Dulux colour strip from a hardware store. It is a pale grey with just a hint of green & stone hues. We decided to paint our living area in it, and it looked so good and went so well with everything that we have used it for the whole house.

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.

Have a look at Dulux Flooded Gum. Come back and let us know if you want a darker or lighter suggestion. Dulux actually have a colour called Warn Grey but it is quite browny. You’ll need to try samples in situ because colours on screen are only a guide.
