@pumpkinpie01 Duck egg blue with cream sounds very restful.
@NoSkinOffMyNose Your suggestion of pairing brown with gold and midnight blue sounds very sophisticated! Thank you so much for uploading pics but unfortunately, for some reason, I can't see them 
@Fourcandlesx Thanks for the brand and name of the paint! I shall ask Dh to run me to our local B&Q tomorrow and see if I can get a tester pot of Valspar Mink Frost - it really does look lovely on your pic and matches the 'vision' I had in my head when looking for grey. I know that Valspar is a good brand, too.
@Cecilia2016 Your scheme sounds lovely and I plan to use large mirrors, too, as my living/dining room is quite big and gets lots of light but I don't want the brown sofas to suck it all up!
@Slinkymalinky1 I love chesterfields! Sadly can't have one as DH prefers high back sofas for neck support. Suppose I do, too. But chesterfields always look so...filthy rich and glamorous 
@greenlynx Where'd you find your soft grey with pale gold curtains? I saw a post on here somewhere asking for preference between shutters and vertical/venetian blinds, and would personally love shutters but probably too expensive given the size of our windows
So will most likely get blinds but I think I'd need some nice curtains to frame the window as not sure if just blinds would feel too bare 
Thanks everyone for your input, though! Some great colour schemes shared and for me assurance that having brown sofas in my living room is not as difficult to decorate around as I had feared
