Personally, I’d say any room (yep, even including kids’ rooms). It’s one big fat misconception that you can only paint certain rooms certain colours. Ignore all that and go dark everywhere if you love it. I have and once you convert to the dark side there is no going back. Just to warn!
Metallics look amazing against dark backgrounds, and I’d always plump for warm metallics – I love coppers, brass and gold. So much more inviting than silver, I think.
Be brave and go the whole hog! I reckon it will look amazing. I’ve painted my hallways and landings the deepest of berry hues and it’s so transformative. A deep dark purple will look super sophisticated.
I tend not to like trim to stand out too much. Firstly I always (always) paint it exactly the same colour as the walls. I use eggshell, so although it has a slight sheen you can barely tell. In my humble opinion you want to draw attention to what’s in the room, more than the room’s trim. So the sublter the finish the better, in my book.
I hope that was helpful! Regrettably, with my crazy busy schedule at the moment I just can’t do as many Design School weekends as I used to. They are still happening, but not every month. I know they’re always fully booked and crazy popular too. I’m thinking of having an #AskAbi session quite often on twitter, so hopefully I might still be able to help you out, even if you can’t make it to a Design School! What do you all think?
