most sane (and probably quite right) people wouldn't dream of including purple in a colour scheme for a chic, well-used room in their home that they want to stand the test of time. I cant blame them, I wouldn't either. I do, however, think people should certainly consider shades of plum, violet and cobalt to accent their neutral decor.
Used cleverly with safer neutral hues; white, grey, cream - purple can lift the tone and add interest to a room, be it in the form of a feature wallpaper or tiled wall, to rugs and other soft furnishngs to minor touches like a simple, pretty tablescape or a huge vase of beautiful purple flowers.
