The superhero party theme is a popular choice for kids parties. It usually features lots of red, yellow and blue for a traditional Boom! Pow! style superhero party. Often kids have a certain superhero in mind so you can work with the colours for that superhero – yellow and black for Batman; red, blue and white for Spiderman, Superman and Wonderwoman; red, black and white for Harley Quinn. Young girls love superhero parties too! Often their choice is for a mix of pink, black and white.
