I want to completely re-decorate our living room but I don't have a great eye so looking for advice! I have a yearning for grey and ochre with splashes of navy blue...so thinking dark grey carpet, lighter grey sofa, ochre curtains, ochre and navy for the other bits...cushions etc. But what colour to do the walls?? Are feature walls naff or will one colour seem boring in such a big room (16 foot by 17 foot). I like Dulux polished pebble colour but should I accent with a darker grey paint on the chimney breast? Or should I just go for an off white so there's not too much grey? Any advice gratefully received!
