These two colors can warm up a room or cool it down; be bright and modern, or vintage and romantic. The best news about this pretty pairing: It looks good in flowers, on favors, and everything in between.

Here, bistro-style tables covered with custom-embroidered linen create the feel of a French cafe. In a footed compote, tulips, ranunculus, and asclepias mingle with olive branches, scented geranium foliage, lemon verbena leaves, and fruiting calamondin branches. Kumquat bunches tagged with guests' names serve as place cards.

Smythson's chic custom cerulean invite suite has a delicate crest and engraved white sans serif type. Orange comes into play as super-subtle edging. To complete the look, go for stamps in a similar shade. Browse championstamp.com, or design your own melon-hued postage online at zazzle.com.

Talk about sweet relief. Cash-cautious couples can cut printing costs way down by taking one of the more expensive elements -- embossing -- into their own hands. It's just a matter of applying a special ink and a layer of embossing powder to a printed place card, then fusing with a heat tool for a few seconds. Voila! Your flourish is sealed.

Rosa Clara's "Bisel" silk-organza gown features a shoulder-accentuating halter with a low-plunging back, the latter serving as an especially dynamic contrast to the petal-patterned overlay and ball-gown skirt. A collection of vibrant garden roses and spray roses nestled into passion vine and olive branches finishes the look.

"Boutonnieres should not be fussy," says Martha Stewart Weddings contributor David Stark, whose new book, "David Stark: The Art of the Party," hits shelves in May. These two snazzy designs -- cornflowers with lemon verbena foliage (far left) and kumquats with citrus leaves, both tied with a snippet of ribbon -- are so simple to fashion that even your least crafty pal can make them.

These calamondin trees (a cross between a mandarin and kumquat tree), set in bright blue stone vessels, were amped up by adding extra mandarin oranges. Just cut five-inch lengths of wire, poke them through the fruit, and wrap the ends around a branch to secure. The trick is to loosely cluster the fruit in groups of two or three, which is how they grow naturally. To make the aisle runner, stencil a swath of linen with blue acrylic paint applied using a triangular cosmetics sponge. For added depth, dab on a coat of light ultramarine blue, then add a deeper cobalt shade.

Slicing into this delectable clementine cake with vanilla-bean icing and fondant will complete your scheme. Emily Lael Aumiller, of Lael Cakes in Brooklyn, sculpted the dainty blooms out of sugar, then hand-painted them in an array of blues.

No matter how you serve it -- between courses as a palate cleanser, with the cake, or as a late-night treat -- Palazzolo's divine sorbetto comes with its own sound track: a cacophony of spoons clinking empty bowls (4gelato.com). Select one of dozens of popular flavors (including tangerine, shown left), or go off-road with a custom order. Plan on having four to six ounces per guest at the ready.

These European treats in winsome packaging are a delightful way to introduce loved ones to overseas indulgences, as well as bid them a flavorful farewell.

To score cinema-worthy shots of your pals and relatives, you'll need a projector that can hook up to your computer and a rear-projection screen. Both are rentable -- your photographer can help you find them, though most towns have photography shops that offer this service. But because many screens stand on legs and we wanted our visuals to extend all the way to the ground, we suspended three yards of Rose Brand gray rear-projection material from the ceiling. On your day, set up the projector behind the screen fabric, let guests choose the backdrop they like best, and offer thematic props; for a Riviera moment like the one above, we put a vintage Vespa to use. Have friends move around, and shoot as few as three still images of them in various poses; then, turn these into a GIF for free at gickr.com. It'll be an animated postcard-come-to-life.
