Is copper the most stubborn colour of them all? Its metallic tones hit the catwalks over two years ago, but the trend has now reached interiors and is refusing to go away. Is it because it stands for the epitome of effortless luxury? Simple and elegant. Or is it the way it holds itself against on-trend blues, as in this photograph of the Cast Iron Bath Company Marseille Cyprium Copper Bath? Whatever the answer, an uncomplicated touch of vintage copper brings your interior up to the now…  …and adds splash of modernity into any bathroom space, just as these timeless copper balls prove. One thing is for sure: whether it’s hand-woven into a lampshade or hung in a traditional interior, it has the power to work with everything from pastel and blush pinks to pale greys, making it one of the most versatile colours of them all.
