help needed

today I'ld like to ask my quilting readers for some help.

I interrupted my first Dear Jane project because I choose the wrong fabrics. I still love the colordiagram, but the Batics and the handdyed popeline (I dyd them) are too hard to sew by hand. Insider do know, there are a lot of the 169 blocks are perfect for handsewing. I prefer the Linda Franz method, but not with this fabrics. Don't think about the quilting. My nearly 50 blocks will end in the center of a medaillion.

In less than 3 weeks I'll be one of the lucky German ladies, traveling to the "motherland of quilting" the States: Washington, Pennsylvania (Lancaster: Quilter's Heritage Celebration), Virginia (Jinny Beyer studio), Shipshewana, Holmes County, Quilter's Hall of Fame in Marion, Indiana, Millersburg, Chicago AND to the Int. Quilt Festival in Rosemont, Ill
I'll have more possibilties to buy new fabrics than my suitcase will take ;-)

But, I'l buy taupe, Japanese fabrics for a new Baby Jane

here comes the question:
which color may I take for the background ????????????????????

I got two interesting tipps, but before I show examples I would like to get your input

Goggle didn't showed my pictures right now, I'll try it later again

THANK YOU in advance
