Deep gray and all the other accents in silvery old wood and cream. This will add drama, allow the other elements to bring ion light and set off the concrete wall as a true feature. If you want light instead of drama, then go for a very pale beige stone. It will echo stone colours in both the concrete and rocks...

Small all in one condo room not sure what color to use for walls after removing wallpaper

New house build.I need a idea for colour matching trim colour on my house. Out side is corrogated iron walls ánd roof in greyfriars,300mm square posts,front and back are in black,inside is spanish white,trim,walls and ceiling in semi gloss. What I am looking for is a colour for the barge boards,front and rear only,rear wood door surround,internal doors (only two,bedroom and bathroom). Was thinking a gutsy orange? Awaiting your views/thoughts

Personally , I wouldn't use that wallpaper -- it doesn't suit the apartment style IMO . I assume she wanted to add some focus and colour , but to me it doesn't work . To make it work ( or at least not 'jar' ) if she does insist on the wallpaper , pick out the burgundy or red of the wattle flower ( or whatever it is ) , and do a wall opposite it in that exact same shade , or maybe the kitchen area if you have good masking skills . The animal skin rugs look great , but the couch is 'lost' -- add cushions in the same red or burgundy as the wall , or go even brighter red or burgundy . Rest of the walls can be left as they are ( depending on wall condition ) or any similar neutral ( aka bland ) grey or cream , or possibly even a light steel blue .
