Funnily enough, those who prefer the colour grey are said to want to insulate themselves from the outside world and keep their passions private. I do, however, like the ironic title "Fifty Shades of Grey", in relation to this. The colour grey is often associated with industrial interiors and urban landscapes. It is quite a calm colour that can be used in various rooms and is quite a nice and versatile colour to design with. Grey works perfectly with white and complements pink beautifully.
