Fall Themed Wedding

Hello all...I am very new to this website..but so far I am loving it....I was wondering if any of you have ever seen or had a wedding with colors like burnt orange and mocha....I think I need another color in there to give it some more life like a pink maybe...I am not really sure....but my biggest problem is decorations for the wedding...The reception is in a very big hall and I need stuff to fill it up without making in look bad or clustered...I don't want to go with pumpkins because it is in aug...and I just am not too thrilled with the pumpkin idea.....If any of you have pictures of weddings with those colors or something similar I would greatly appreciate you sharing them with me!! Thank You!!
