Dates and Colors

Dave and I have officially decided on Fall 2013 for the wedding.  We are thinking of late September or early October of next year.

We will have to keep this in mind:  Wedding Dates to Avoid.

Also, we have decided on colors, well at least somewhat.  I know that we want a dark purple (plum?) as the main color with white or ivory.  We probably need an accent color, but aren't sure what - black, silver, gold, green, orange - so many options.

Any ideas for an accent color?

Also, please share your wedding colors below.  I love seeing the different combinations.
