We have a cosy sitting room that’s a dark raspberry colour with a teal velvet sofa, cream linen curtains with a multi coloured ‘water paint’ pattern, that picks up the other colours. It’s the only strong coloured room in the house and makes a surprising statement.
I think reds or purple is something I wouldn't risk unless you really know what you are pairing it up with in terms of furniture and accessory colours... I love blues, they are calming, beautiful yet easy to live with and easy to pair with other colours...
We have one a sort of duck egg colour with mustard curtains and a tan leather sofa and one forest green with navy. Neither room feels dark or oppressive but they both have original picture/plate rails so are white above those. I like colour ❤️
Try some colour! The worst thing that can happen is you have to re paint.
I've got purple/plum/pink. Sounds awful but it's so cosy -and a bit chintzy-. We have the dreaded 'feature wall' with a cream background and big flowers in the above colours. The other walls are a dark purply plum. I love the texture of our cosy ( purple) rug and the ( purple) throws on the dark brown leather sofas. Curtains are lined silky ( and purple!). I am quite a bold person and definitely go for the 'more is more' school of thought. It can be re-painted!. I've had nothing but compliments on mine . Looks lovely with my tacky fairy lights glowing in the evening.
we have sort of goldy/sandy coloured sofa, goldeny beige (so ties in with sofa but lighter and not too samey) carpet and terracotta curtains. I want to change the curtains but not got anywhere with colours yet. the gold and orangey colours are really nice and cosy, I am just a bit bored of the curtains after 10 years of looking at them every day. Personal favourite colours are purple with silver/grey, teal green with gold or sage green which I love and think is very calming (yet don't have in any room in the house!)
