I haven't seen this particular design, but one very close to it, in person. It is striking. It contrasts well, and at a distance it doesn't look odd. The purple in the one I saw was so dark you had to get close to see that it was purple. I didn't care for the colors, not my choice. But the quilt was striking. :)
I was refering to the author's original picture when talking about the design.
the second one I like. the purple is an accent. It's like looking at Irises, they are purple with greens. :)
