Eggplant purple (often called plum) is a rich, dark romantic color that is popular for fall and winter weddings. For spring and summer weddings, pair it will greens, blush pink or other soft purple shades.
Love the purple walls (I can't find the source of this image which is mighty annoying) I love the color scheme but rather in a bedroom or living room. Dark purple walls, gray wainscot, white ceiling and marble gray floor. Metal or silver details.
