Good choice. The orange/red brings out the colors. The purple is nice, but I don't care for the blue - it blends in too much

Purple!

I vote red, makes it really pop!

I like the red-orange and the purple. I am at that age where I would like to be a red hat lady with a purple dress. But your choice is to bring out the red in the backing or to bring out more purple. I think maybe the red would be best.

I prefer the orange

Purple or orange - both are equally nice.

Depending on if you really want a bright look, I'd pick the orange...wow! Yet, if you want a little more of a soft, elegant look, go with the purple.

Alernate orange & purple

I like the orange.
