Hi Tashaa
Unfortunately there are very few brown rose options to choose from but if you are open to other flowers here are a few suggestions that may be of interest.
One flower that is difficult to get hold of but might be suitable could be chocolate cosmos, a daisy-like flower in deep rich brown, with a real chocolate fragrance.
If you want something dramatic and exotic then anthuriums might be worth considering they are unusual, rich and glossy flowers. Ask for "Tropic Night" for the darkest shade, almost black, "Choco" for a plain-chocolate colour, or "Castano" for something more brunette.

Wedding Flower QuestionIf you would like a more traditional look then Germini come in various deep cream shades with deep brown middles and you could always accessorise with say brown feathers or Hypericum berries "Dolly Parton" and the lovely "Vendella" roses, it really does depend on the style of your wedding and the overall feel that you are looking for.

One final suggestion for a rose is Suraya - its quite a dark orangey/brown rose.
We hope that you find the suggestions useful!
