Unicorn Party Color Scheme

Before I get into the decorations, food ideas, and party games, I wanted to highlight the color schemes you could implement into your mythical unicorn birthday party. 

You have two options when it comes to a unicorn color scheme: beautiful pastel pinks, purples, blues, greens, and yellows, or on the other end of the scale, bold and bright yellows, pinks, blues, and purples. Of course, the choice is really up to you, but in this article, I will include ideas for both options so you can decide which one suits you best.

Unicorn Party Invitations

Invites are one of the first things to think about when planning a birthday party, and thanks to technology, there are now two ways to go about this. First, you can head down the traditional paper invites route that you hand out or mail to your guests, or you can make your invites digital and purchase a customizable and downloadable invite that you can email or text to your party attendees. 

I have used both types of invites, as I love how personal it is to write out and hand out traditional invites, but digital invites are quick, convenient, and affordable.

For mythical unicorn parties sticking to a pastel color scheme, these adorable Pastel Unicorn Invites are the perfect way to get your guests excited for the party. Alternatively, I love these Flower Crown Unicorn Party Invites for unicorn parties opting for a brighter color scheme.

If you’ve never sent out digital invites before, you’ll be happy to know that the process is relatively straightforward, even if you aren’t the most tech-savvy. All you’ll need to do is purchase an invite, like these Pastel Unicorn Digital Unicorn Invites or these Bright Rainbow Unicorn Digitial Invites, and follow the steps that the website lists to edit and customize the relevant information. Once you’ve finished editing, you’ll be sent a digital file you can email or text your guests. It is as simple as that! 

Unicorn Theme Birthday Party Decorations

I’m guilty of getting carried away with supplies and decorations for birthday parties, but in my opinion, they tie the theme together. Of course, you can choose to go overboard or stick to a budget when it comes to decorations, but I highly recommend a balloon arch, tablecloths, cups, plates, a banner, and a garland. 

Balloons

I was once afraid of balloon arches because, let’s be honest, they look challenging to put together. But once I purchased a balloon arch kit and assembled it for my little one’s birthday, I realized they’re far easier to construct than they seem. 

Two of my biggest tips for balloon arches are: 

  • Purchase a balloon arch KIT
  • Save yourself the hassle and invest in a balloon pump

Balloon arch kits like this Pastel Unicorn Balloon Arch Kit and this Bright Shimmer Balloon Arch Kit come with very handy decorative tape that you thread the tied balloons into. This tape makes a world of difference when constructing a balloon arch, and in no time, you’ll feel like a professional creating expensive-looking arches all by yourself. (Trust me, it is a huge confidence boost.)

Garland

A few different garland ideas suit a bright or pastel-inspired mythical unicorn birthday party. First is this Gold Happy Birthday Garland that features a unicorn head centerpiece and unicorn end pieces. Second is this Unicorn Happy Birthday Garland with the words happy birthday written through the Unicorn’s body. And third is this Simple Unicorn Happy Birthday Garland with unicorns, rainbows, and stars dotted throughout. 

Banner

Banners, in my eyes, have two purposes, they not only are a fun way to cover up a blank space in your venue, but they also create a lovely backdrop for photos. 

A banner idea for a mythical unicorn pastel birthday party is this Happy Birthday Unicorn Banner that measures 5 feet by 3 feet. Brighter unicorn birthday parties, on the other hand, would be better suited to this Colorful Unicorn Happy Birthday Banner, that’s slightly larger at 6 feet by 3.6 feet.

Tablecloth, Cups, and Plates

Regardless of your color scheme, this Unicorn Party Supplies Kit will be perfect for your unicorn birthday party. The kit comes with 2 tablecloths, 25 dinner plates, 25 dessert plates, 25 napkins, 25 cups, and 25 straws, meaning you can put together the ultimate unicorn-inspired table spread. 

Other Decorations

Some other additional decoration ideas that you can incorporate into your mythical unicorn birthday party include these Foil Number and Unicorn Balloons, these Aquamarine Foil Fringe Tinsel Curtains, and these Honeycomb Unicorn Centerpieces

Activities and Games

Games are often the highlight of the party. Aside from your typical musical chairs, musical statues, and pass the parcel, there are a few unicorn-inspired games that your guests can play while attending your unicorn birthday party. 

Inflatable Unicorn Ring Toss

This Inflatable Unicorn Ring Toss game also doubles up as a decoration and even a photo prop! Once inflated, the little ones simply need to see who can get the most rings on the Unicorn’s horn.

Unicorn Bean Bag Toss

A more affordable tossing game is this Unicorn Bean Bag Toss. Hang the banner and have your guests take turns to see who can score the most points by tossing bean bags into the holes. 

Pin the Horn on the Unicorn

We’ve all played pin the tail on the donkey, but as you’re throwing a unicorn birthday party, it only makes sense to Pin the Horn on the Unicorn instead.

Unicorn Sticker Activity

I don’t know what it is with kids and stickers, but speaking from experience, stickers are always a hit. These Unicorn Sticker Activity Sheets are a great little party activity as your guests can decorate their very own unicorns. 

Unicorn Pinata

It’s just as fun to watch someone hit a pinata as it is to be the one actually doing the hitting. This Unicorn Pinata will make a great addition to your unicorn party games, and your guests probably won’t stop talking about it. 

Unicorn Dart Board

Technically not a dart board because the kids will be using balls instead of darts, but this Unicorn Dart Board is another excellent throwing game that your guests can use to battle it out to see who is the ultimate throwing champion. 

Unicorn Rainbow Scratch Masks

Finally, an activity that your guests can also take home with them as a party favor are these Rainbow Unicorn Scratch Masks. First, each guest will get their own mask to decorate. Then, they will take one of the included sticks and scratch away at whatever design they wish to reveal the colors underneath. 

Unicorn Themed Party Food

Regarding food, I like to put together a grazing table with a range of different treats and snacks as opposed to a sit-down meal. So here are some of my favorite unicorn-inspired foods you can serve at your party. 

Unicorn Poop Cookies

Unicorn poop cookies are very easy to put together, as you’ll simply need your trusted sugar cookie recipe, some bright food dye, and star sprinkles. Whip up your sugar cookie dough and separate the dough evenly into separate bowls, adding in your chosen food dye. 

Take even pieces of each color dough, and combine, so you’re left with a rainbow sugar cookie swirl. Then, roll the dough into a snake shape, and form the cookie so it looks like a poop. Bake accordingly and top the cookies with star sprinkles once cooled.

Unicorn Cupcakes

Everyone loves cupcakes, and transforming a regular cupcake into a unicorn cupcake is a very straightforward task. 

Start by baking your own cupcakes or picking some up from the store. Next, top the cupcakes with white frosting in a swirl design. Next, add Multi-Colored Sprinkles and mini marshmallows cut in half to resemble the Unicorn’s ears. And finally, finish off the cupcakes with a Gold Candle horn, and they’re ready to go!

Unicorn Cinnamon Rolls

Run to the store and grab the trusty Pillsbury Cinnamon Roll packets. Bake the rolls per the instructions on the box, and separate the included icing into three different bowls. Add drops of pink, purple, and green icing into the bowls and spoon the icing one by one onto the cooled cinnamon rolls. Finish the rolls by topping them with Unicorn Sprinkles.

Unicorn Sandwiches

Sandwiches are one of the easiest foods you can serve at your party, and you can fill them with whatever filling you wish. To make them Unicorn themed, simply cut them out with Unicorn Cookie Cutters and, voila, unicorn sandwiches. 

Unicorn Popcorn

To make unicorn popcorn, you’ll need a bag or two of plain popcorn, pink and blue candy melt, and pink food spray. Pop the popcorn as per the bag’s instructions, and spray lightly with the pink food spray. Next, melt the candy melts in the microwave in separate bowls, stirring every 25 seconds or so. Add in ½ a teaspoon of coconut oil and drizzle both colored candy melts onto the popcorn. Place your popcorn in a Unicorn Popcorn Box, and you’re done!

Cake Ideas

When deciding on a cake design, there is only one place to go: the mothership, Pinterest. Pinterest has a vast selection of mythical unicorn birthday party cake ideas you can recreate or show as inspiration to a local bakery.

Outfit for the Birthday Child

If you’re having a unicorn birthday party, of course, the birthday child needs to be matching with the theme. For girls (or boys), you can’t go wrong with this beautiful Unicorn Sequin Dress. However, this Birthday Girl Unicorn T-shirt is an excellent option if you’d prefer a comfier, more understated one.

For boys, this Dancing Unicorn T-shirt or this Unicorn Security T-shirt would work nicely as they tie in with the theme and can be worn throughout the year. 

Party Favors

Party favors are optional, but if you want to send your guests home with something to remember the party by, this Unicorn Party Bag Filler Set is an affordable and cute option. 

Alternatively, you can create your own goodie bags with Unicorn Party Bags, Unicorn Head Bands, Unicorn Notebooks, and Unicorn Straws.

Or use Unicorn cookie cutters and make cookies for your guests to take home.

Thank you Cards

Once your guests have all gone home and your little one has opened all their presents, it’s time to write and send out thank you cards. Thank you cards like these Unicorn Thank You Cards are a great way to show your appreciation for your guests, their gift, and their attendance at your party.
