Blue Wedding Cakes

Some cakes are just too pretty to eat. And some cakes are just too good not to. Let your blue wedding cake be both. After filtering bakers near you on The Knot Vendor Marketplace to find a pro who will make your cake into a sight to behold, show them these images to help them execute your vision.

5. Two-Tier Pale Blue Cake With Cut-Out

The subtle pale blue hue lets the fabric-like cut-out, which is adorned down the side, stand out. We suggest cutting the cake on the other side to preserve the beautiful handiwork here.

6. Blue Wedding Cake With Berries

We love the variety of blues on this stunning wedding cake. From the textured-looking fondant to the blueberries adorned around the edges, this cake is full of details.

7. Blue Sprinkled Wedding Cake With Fondant Bows

Lean into your inner child and go for a cake covered in blue sprinkles and fondant ribbon around the edges. Adding a personalized cake topper is, well, the icing on the cake.

8. Three-Tier Pale Blue Cake

For a blue-themed wedding, this three-tier, Regency-era cake is perfect. The vintage details and ornate white frosting take this to the next level.

9. Bright Blue Vintage Vases

These blue chic vintage vases would be perfect for blue wedding flowers or an escort card table centerpiece. You could also repurpose them as a place to put cards or as simple decor used around the space. Either way, they're sure to make a statement.

10. Light Blue Taper Candles

These light blue taper candles add romance to any table setting. We love how airy and soft this shade of blue is and think it would pair well with a white or cream runner.

11. Blue Escort Card Display Wall

If you plan to have an escort card display, making it blue is an easy way to incorporate the color into your wedding theme. Surround it with florals or greenery to really make it stand out.

12. Blue Wood Signage

Signage is also a great option for a blue wedding theme. Whether it's the background color like it is here, or you use blue fonts or calligraphy, it's a quick and easy way to highlight it.

This elegant boho blue runner is the perfect complement to a wood table. We love this blue wedding idea for a coastal wedding or an elegant rustic affair.

14. Blue Uplighting

If you want your dance floor to feel like a place where people can really let loose and bring their best moves, consider uplighting that fits right in with your theme. It'll make your guests feel like they're at a club or a show and make the vibes that much better.

15. Blue Chinoiserie Dishware

If you're going for a more vintage vibe on your wedding day, chinoiserie dishware is a great way to lean into that while keeping your wedding colors top of mind. It's dynamic, eye-catching, and elevates any tablescape.

Shades of Blue for Wedding Colors

Options are endless for incorporating shades of blue into your wedding theme, including dusty blue, sky blue, royal blue, navy blue, baby blue, ice blue, cerulean, indigo, cobalt and more.

What Colors Go Well With Blue for a Wedding?

The great thing about blue as a wedding color is that it pairs well with an endless array of colors. You can let it be the star and add supporting colors or you can use different shades in combination. Green is a great option if you're going for a nature or outdoorsy vibe, blue and pink wedding colors are a good complement if you want something bright and colorful, and blue and orange wedding colors can work if you want something cheerful. For a luxe and opulent wedding, consider navy and gold, navy and maroon, blue and silver or gray. For traditional blue wedding color schemes, consider blue and white, off-white or cream. Bottom line: There aren't many colors that don't vibe with blue.
