A rainbow party is a great theme choice for so many reasons! (1) It's not seasonal (so it's appropriate for any time of year), (2) it's not just for birthday parties, (3) it's so easy to find coordinating party supplies - party decor and party supplies can be any color...red, yellow, blue, purple orange or green, and (4) the bold, bright colors of the rainbow simply make for the "cheeriest" decor!
Basic red Solo cups will match perfectly and no worries if you can't find red napkins - blue or yellow or orange or purple or green will coordinate just as well. Actually, the more variety of colors in partyware the better, if you ask me! You can choose a different color for each party item - like red cups, yellow napkins, blue dessert plates, green flatware and a purple table covering for example. This means more time for fun with less-stress in the party planning department!
And to top it all off perfectly, you can very simply and inexpensively accent your party area with eye-catching details using pretty party printables that bring your cupcakes, goody bags, water bottles and food table to life! Bold, bright patterned decor will complete the look and really complement your solid-colored partyware.
And last but not least, let's not overlook that this is a super theme for a St. Patrick's Day party. Remember that "pot o' gold" is at the end of a rainbow! What a pretty alternative to a party that's otherwise simply green..but of course, you can still add the shamrocks! :)
