There are lots of great ideas for Halloween birthdays, but what if your birthday is in October but not on Halloween? October can be about more than just Halloween. Take advantage of rich fall colors and the joys of the chilly season to make your October birthday special. Birthday invitations Skip the black and orange of Halloween and opt for richer fall colors. Gather your inspiration from the changing leaves and harvest colors. The rich reds, bright yellows and earthy browns can make perfect birthday invitation colors. Leaves, twigs and gourds make great accents on your fall birthday invitations. Gem stones for October birthdays are opal and the pink tourmaline. Both of those colors can look great on your birthday invitations, too. October theme ideas If youâre looking to separate your birthday from Halloween, there are many great options for you. Since the October weather can be rainy and/or cold keep your activities centered around indoor activities. October days can be warm, but the nights can be pretty chilly. If you do plan outdoor activities â a hayride for example â make sure you let your guests know in the birthday invitation so they can bundle up.
