Thanks for the advice @Juliet Docherty & @sandrasal I haven't bought the sofa yet but think this is the style I'd like. The room has 2 large windows so gets a fair bit of natural light in. Not as much as @sandrasal but think its sufficient to call it a well lit room. Originally i was thinking the 'Dulux One Coat - Teal Tension - Simply Refresh Feature Wall Paint' below but maybe a lighter, duller version of this would be sufficient and let the sofa be excentuated. https://www.wickes.co.uk/Dulux-One-Coat---Teal-Tension---Simply-Refresh-Feature-Wall-Paint-1-25L/p/236892 What's your thoughts on the mustard arm chair? I think it could look amazing contrasting the sofa? Again, thanks for the help.

Tamp75 glad to hear you feel it works in your room. I'd be really interested to see a picture if you didn't mind sharing? Thanks for the colour suggestion Daisy. It's a nice colour but I'm quite keen to go dark if i can because the other rooms are all light and feel quite airy which is lovely but I'm really hoping to go a bit more dramatic in this one. Out of interest was your suggestion because you felt a dark colour wouldn't work or because it's quite a popular/trending colour at the moment?

You don’t say for which room, but Pinks, greens and greys would go well.
