LS Pagan Tarot-4 of Wands

Disa

This card very obviously depicts a wedding. She in her white cloak and he in his black. Does this represent the duality of "good and evil" joining hands to become one in order to show that all things necessary to maintain the balance?

There are 7 people in the card, a lucky number for a momentous occasion. The 4 holding the wands offer their support and/or stability to the couple. The book tells that the four are dressed to represent the elements:

Yellow for Air
Red for Fire
Blue for Water
Green for Earth

Often the 4 of wands reminds me of confinement within 4 walls, but this card seems open and cheerful.
