Whilst I like white interiors and I'm not necessarily somebody who likes to have an absolute riot of colours at home, I do firmly believe that every interior needs touches of black. Black adds depth, a focal point, interest and is the ultimate elegant colour (or non-colour, but let's not get into that argument) for interiors and a sophisticated choice. It is of course not the most cheerful colour, but it will make details really stand out and make a statement.
The seasons do of course play a role. I tend to bring out more black in winter than in spring and whilst I do like the backdrop (i.e. the walls) to remain white because I like the light and airy feel, black does bring a level of drama that would otherwise be missing. Using black as an "accessory" means that it's not overbearing, claustrophobic or gloomy. It makes whites seem whiter and adds the depth that all-white interiors seem to sometimes miss. It works beautifully in combination with some natural touches like branches, with glass and metallics, paper decorations and warm fairy lights. It can be patterned or plain, used on wood, canvas, ceramics, metals and fabrics. Each surface will change the way it appears: glossy or matt, rough or sumptuous, delicate or earthy. The result are always striking and stand out in a way that a pale driftwood frame on a white wall never could.
Maybe it has something to do with my bear-like instinct to hibernate in winter or with my desire to combine the elegant with my rather bohemian style. Either way, for now I'm happy with the way it grounds my home and - to an extent - myself.
