There are birth colors.....birth stones, and flowers which can be used in your theme birthday. Here is the list
•January: carnation or snowdrop; garnet •February: violet or primrose; amethyst •March: jonquil, daffodil or narcissus; aquamarine •April: sweet pea or daisy; diamond •May: lily of the valley; emerald •June: rose; pearl •July: larkspur or water lily; ruby •August: gladiolus or poppy; peridot •September: aster or morning glory; sapphire •October: calendula or marigold; opal •November: chrysanthemum; topaz •December: narcissus; turquoise
Also there is Native American Indian Horoscopes that depict the totem animal your birth date represents. You can google it and maybe work a theme sorrounding that as well.
Neon and black--Maybe you can have some "VIP's" dress up in black and everyone else dress up in neon... Haha, everyone in neon could dress up like Nikki Minaj! :)
or combine what natalie and blakbeltv3 said... tell everyone to show up in black, the you get to come out in neon!
say its a an all black party and tell everybody to wear all black and then show up all in white.
