Help! Opinions Wanted

So I'm in the middle of putting a new book together for spring market.  The first draft of the book is done.  Quilts are being made.  Patterns are being tested.  Patterns have already started being revised. 

I am going back and forth on one of the quilts, and thought I would ask your opinion.  This quilt is made with Birch Organic Fabrics.  The line is Circa 60 Beach Mod.  I am putting them together with solids.  There will be two colors of solids, white and one other one.  The problem is I can't decide!  I keep changing my mind. 

The two options are rust

or mustard.

What do you think?  Rust or Mustard? 

I see the rust and I am in love with the rust, but then I see the mustard yellow, and I really like that option too.  Both look good, so what do YOU think????
