I don't think there's a right or wrong answer to this question - it really is down to your own personal choice.
Here are some things to consider...
+ Using your dress or wedding theme colour for your wedding invitations alerts guests to the colour that the bridal party will be wearing, so that they can avoid it when choosing their own outfit.
+ If you want to use the dress colour, remember that it doesn't have to be an exact match. Your guests will be seeing your invitations months in advance of the wedding and won't remember that the invitation colour was tonally a little different.
+ Matching your colours throughout the wedding can be difficult e.g. not all pinks are the same colour! If that's the case, you may want to focus the colour on the dresses and flowers, and keep everything else a neutral colour: black/white, silver and gold are great neutrals.
+ Keeping your invitations monochrome by choosing one of our Graphic Invitations, keeps your colours a surprise for guests on the day and allows much more flexibility for your on-the-day stationery.
+ If you have chosen a particularly unusual colour for your bridesmaids, keeping your invitations and on-the-day stationery neutral is a lot less stressful.
In my opinion, less is more but that doesn't mean your invitations can't be colourful. As I've already said, your guests see the invitations months in advance of your wedding, so there's no reason why you can't have colour in your invitations, but keep your on-the-day stationery neutral. A very popular choice for AniMac clients has been to have a colourful Wooden Heart Wedding Invitation, with neutral on-the-day stationery featuring one of our Graphic Designs. And I think this is the perfect way to incorporate both aesthetics!
