Blue wedding invitations can actually have several different looks as far as designs that may fall into this color theme. Shades of blue can also range from light pastel to dark navy. Here are some design examples showing not only different color tones but also different ways of using blue as part of your invitations:
This invitation card itself has a blue colored background as part of the design.
This pocket style uses a lighter shade of blue for the design on a white invitation card.
This unique selection uses a navy blue wrap around an ecru card outlined in a gold foil border and all tied together with a matching navy ribbon.
As always, these are just a very few examples of the blue wedding invitations that are available, especially if shopping online.
