I am looking for a accent/secondary color that will look perfect with....?

You've had good suggestions - I especially like the pale yellow/green ideas. But!! The thing about weddings....hah! What you want isn't always available. Choose a couple colors you wouldn't mind...but be thinking: how are you going to use this accent color? Will it be the flower girls dresses, or tablecloths, or flowers? Then, go to the actual vendor and see what choices THEY have available. They'll probably limit your options for you by what they have in stock, etc. Sounds like you have a pretty specific "primary" color so maybe the secondary should be a more "common" color to give you more options of places to use it. I for example completely changed my wedding color ideas once I got to the dress shop and had to accomodate a bridesmaid dress style that would look good on all my ladies - which in turn limited what colors I had to choose from. Dress colors are the hardest - so start with that, and it's usually easier to find matching flowers, tablecloths, paper decorations, etc. Good luck!
