There are many different ways to settle on a color theme for your wedding. Some brides have known since they were little girls what colors they wanted to use in their wedding. Some grooms have a strong opinion about one color or another. Still, other couples choose seasonal color and some choose colors which will coordinate with their wedding flowers. There is no rule for how to choose a color theme, or how many colors to choose. Extend the color theme to your invitations _ Some people want every part of their wedding to be color coordinated. Others are less sure. For some people, the traditional ivory paper is what they always imagined as part of their wedding day, while others want their invitations to be as unique as their relationship with their future spouse.
Another thing you can choose to do, if you do not have too much money allocated for this particular thing, is to peek online and get inspired and make your own wedding invitations. There are many sites and forums where people log in and talk about the things they have done or are still doing for their budget wedding and you can get some good ideas about how to have some very beautiful wedding invitations without spending too much money.
