When I googled the quiilt name, I found a youtube video of someone paging through the book, so I was able to see the quilt! (It's the second quilt in the book.)
As DH always says when I ask for his advice on a design element, 'It depends on the effect you want.' I love single color quilts; I think greens would have a more subuded, calming appearance, and a multi-colored scrappy would be more lively. I think either would be great choice.
