Using pink in common areas isn't exactly the most mainstream way of decorating. Typically, pink is associated with children's rooms or a rather feminine living space — but that should really change. There's nothing wrong with adding pink — it'll only chic things up a bit!
Ok, so adding pink to living spaces will ultimately make it lean towards the feminine side but that's just something you have to be willing to accept — and it'll totally be worth it. Start out subtle by adding blush pink curtains to a room that already has neutrals. The curtains will add just that small touch of femininity without being overpowering. Or, reupholster your sofa with a pale shade of pink!
If you're feeling a little bold and daring (after all, Room for Color 2011 is starting soon) head to your local hardware store and pick up some pink paint. Accent the new wall color with gold, blue and white accessories and you'll find that everything will flow so well together. Here are some great examples of pink both subtle and bold:
