Embracing a rainbow wedding theme on your big day? We love it! If you’re trying to find some creative ways to infuse your big day with some serious multicolour magic, we’ve got you covered. Whether you’re looking to brighten up your menu, make your attire a touch more whimsical or incorporate some bold rainbow wedding decorations, you’ll find something—maybe even a few things—that fit the bill on this list.

Here are a few drop dead gorgeous ideas for your rainbow wedding theme.

Wedding invitations

Let your guests know about your wedding theme from the get-go by sending out rainbow-themed wedding invitations. If you want to really knock it out of the park, follow suit with your wedding website and choose a bold and bright theme for your background and font.

Balloons and pom poms

Take your altar from meh to magical by decorating your wedding ceremony arch with colourful balloons and paper pom poms. You can mix in some flowers, ribbons and other bells and whistles to make it extra eye-catching.

Bridesmaid dresses

You probably want to wear white on your wedding day, but your bridesmaids don’t have to! Get them in on your rainbow wedding theme by asking each of them to wear a different colour of dress. Be sure to ask everyone for their top pick so that each maid gets a shade that they feel comfortable and confident in.

Colourful groomsmen socks

For the gents in your wedding party, gift them with a pair of socks across the rainbow spectrum. Don't forget to snap a cute pic like this one.

Rainbow wedding bouquet

Work some rainbow magic into your wedding flowers by carrying a multicolour bouquet down the aisle. You can go with hand-dyed blooms for something bold and bright or do a more muted, natural rainbow of flowers.

Here's a colourful rainbow-theme wedding flower idea. Have your florist design a rainbow spectrum of bouquets—one shade for each wedding party member.

Colourful ceremony

If you're planning a handfasting ceremony, use a rainbow of ropes or ribbons to tie the knot.

Forget about being showered with rice or flower petals after saying your ‘I dos’—ask your guests to toss colourful confetti your way, instead.

Rainbow smoke

Amp up your wedding portraits by posing in front (or behind) a veil of ROYGBIV smoke.

Another solid option for your wedding portraits is posing in front of a graffiti mural. Many industrial-style venues have ‘em, but if all else fails, you can take to the city streets for your shoot.

Your wedding bar doesn’t have to be boring! Skip the plain ‘ol gin and tonics and vodka sodas and serve an array of colourful cocktails. You can do this with teas, sodas, juices or mocktails if you’re going the non-alcoholic route.

Rainbow shots

And for something on the boozier side, you can ask your bartender to create a rainbow display of colourful shots.

Make your wedding table decorations match your rainbow wedding theme by using colourful centerpieces, bright dishware, drinking glasses and linens. The brighter and bolder, the better.

Sweetheart table

Dress up your sweetheart table with multi-coloured streamers, candles, bunting and bouquets to envelope yourselves in colour. You can make bright and beautiful decorations with paper, fabric or wool. Ask your florist to use bold blooms in your table centerpiece, too!

Make your head table or sweetheart table stand out by putting up a whimsical backdrop behind it. You can use different shades of linen (like this couple), paper, balloons and/or flowers to really make it pop.

Paper lanterns

Take your rainbow wedding theme from floor to ceiling by filling the roof of your venue with colourful lanterns. If you want to save a bit of cash, you can achieve a similar look with balloons.

Giant Balloons

Here's a fun backyard wedding idea. Decorate a pool or garden with oversized balloons in a rainbow of colours.

Rainbow lighting

Another great way to add colour to your reception space is with up-lights and spotlights.

Wedding cake

Take your wedding dessert table to the next level by topping it with a rainbow wedding cake. If you don’t want your display to be too bold and bright, you can ask your baker to frost the outside with a more elegant buttercream or fondant design and do a multicolour interior, so you get the best of both worlds.

If you prefer cupcakes to a sky-high traditional wedding cake, go with a similar style in mini form. Don’t forget to top ‘em with sprinkles and colourful toppers, like maraschino cherries.

Candy bar

Give your friends and family a taste of the rainbow by filling your sweet table with colourful candy treats like Skittles, Sour Patch Kids and Starbursts. Your guests can even take some home with them at the end of the night as wedding favours (killing two birds with one stone is always a good thing).
