Even though i am sometimes a bit out there i will say i went with the traditional colours for my wedding dress ...however...if had i been brave enough to go down this path, here are some of my favoutite coloured gowns that i think could make stunning wedding dresses!
Vera (like madonna only needs the first name)
Via Coco & Kelly
Mila Kunis's Ellie Saab Oscars dress - stunning
(ok i admit i did go looking at chic collections for this dress but no where to be seen!)
Emily blunt via Table Tonic
