Colors.....

I am having a Spring Outdoor Wedding, and our colors are Hunter green and either blue or lavender. Here is my question: How do I incorporate both colors, in the appareal? OR would it look okay to put the groom in a black tux with the green tie and vest, his groomsmen the same, and the Bridesmaids in the same. How do you determine who matches whom?? And then what yould the maid (matron) of honor wear?? I am so confused, please help!!!
