It’s one of the most versatile colors in the world — perfect for making any kind of celebration extra special. Here are some of our favorite blue themed party ideas for adults!
1. Book a totally blue venue on Peerspace
Whether you’re throwing a birthday party, anniversary celebration, or even a company event, one thing is for certain—you need a venue to host your grown-up blue soiree. Worried about finding a venue with the right mood for your event? Don’t worry, Peerspace has your back.
As the largest online event vendor in the world, Peerspace has tons of beautiful venues all across the globe, even uniquely blue ones. Chillax by a stunning blue lagoon, mingle in a moody blue dance studio (pictured above), or host a pop-up event in an urban blue storefront.
You can filter search results by their overall aesthetic and even certain keywords, like “blue”, “coastal” or “beachy”. And thanks to your friendly local host, you may be able to add on features like catering, entertainment, and party decor to your venue if you like. Browse venues in your city until you find the perfect space for your blue-themed get-together!
2. Dress up your venue with decor

Speaking of decor, your venue might have tons of blue already, but it could always use more! Dress up your venue with blue balloons, streamers, table spreads, and other fun decorations until it’s drowning in a sea of blue. Decorate with different shades of blue for variety, or stick to a single shade for consistency, like royal blue or powder blue.
Don’t forget to throw in some neutral shades to add some sophistication to your color scheme. These are blue themed party ideas for adults, after all.
3. Plant blue flowers at a gardening party

This blue-themed party idea is ideal for outdoor lovers! If you’re looking to bring a touch of blue to your next big get-together, head outside for a garden party surrounded by gorgeous blue flowers. Imagine sipping tea surrounded by an ocean of vivid blue flowers. Cornflowers, periwinkle, irises, and Hyacinths all make gorgeous arrangements. If you want a more hands-on outdoor activity, host a gardening party and plant some blue flower starts with your friends!

4. Celebrate the big blue world at an undersea party

Want to celebrate the biggest, bluest body of water in the world? Pay homage to the ocean with an undersea-themed party. Decorate with draping blue curtains to evoke ocean waves, serve up seafood dishes, and turn down the lights for a moody and mysterious undersea atmosphere. It’s also sophisticated and works for everything from birthday parties to charity galas.
It probably won’t surprise you to hear that Peerspace can help you book the perfect undersea-inspired venue for your party! For instance, check out this stunning Cape Cod beach house in San Clemente. It has space for 30 revelers, panoramic ocean views, and even a saltwater pool with a waterfall out back.
5. Make a splash at a blue pool party

Looking for blue themed party ideas for adults that are perfect for summer? Celebrate water by hosting a pool party! You and your crew will have a blast splashing around in crystal blue pool water. If you’re looking for something more lowkey, work on your tan while enjoying some refreshing margaritas poolside. It’s a refreshing, fun, and relaxing idea for adults who love the water. Don’t have access to a pool? Then rent a private one on Peerspace!
6. Mix up blue concoctions at a grown-up cocktail party

What’s something that instantly makes a party more grown-up? One word — tequila. Elevate your party by serving up some blue-themed cocktails to your guests, like a classic blue Hawaiian or an off-beat blue margarita. You could also mix up a unique blue drink just for the occasion! Let your imagination run wild by hosting at a luxurious Peerspace bar with everything you need to get started.
7. Appreciate the ocean at a tropical party

The tropics are home to the most dazzling beaches in the world. If you wish that you could stretch out on that gorgeous white sand, don’t fret. In fact, you don’t have to splurge on a plane ticket — bring that same vibe to your next big party! Evoke the vibe of the tropics with lush plants, vibrant flowers, and soothing tropical music. Since this is a blue-themed party, you’ll want plenty of blue touches to celebrate the ocean, like an ombre wave cake.
8. Add soul to your event at a blues club

Who says you have to decorate with the color blue to host blue themed party ideas for adults? Bring a hearty helping of soul to your party by paying homage to blues music! You could head out on the town to enjoy a local blues club or ask your Peerspace host to help you hire a blues musician to add a soundtrack to your party. If you need A/V equipment or a sound system at your venue, they can also help you out!
9. Sample blue cheese and wine at a tasting party

Wine tastings are an awesome way to bond with friends and family without breaking the bank. Put a blue-themed spin on your next tasting event by curating some chromatic blue selections for the occasion. This could be something literally blue, like blueberry wine, or a wine with a blue bottle or themed label. Don’t forget to also serve the blue cheese and blue corn tortilla chips!
