HELP with colors, please!

I am getting married in June at a beautiful, ornate theatre.  The colors inside it are crimsons, burgundies, golds and creams.

I am having a HORRIBLE time nailing down a color scheme for the wedding.  I know that my bridesmaids are in gold dresses and I am wearing a cream colored gown, that is being made for me out of many different layers laces and textured fabrics.

I am planning on having a more diy-vintage type wedding, especially since the reception is outdoors.  But the ceremony I feel should be a little more classy, to match the surroundings of this theatre.  

What colors should I use that would still go with gold and feel summery?  And would it be appropriate to have a different color scheme for the outdoor reception... or would that be too much work?  I appreciate any help and advice... thank you!
