Sage or a hunter Green needs to replace that green (think blue undertones here - not yellow undertones as the stripes in this fabric appear to be cools). Really will depend on your pattern as to what you want to have stand out. Softer toned additional fabrics might make those yummy stripes really pop whereas the brights might overpower the focus fabric. Just my humble opinion.

Your choice is Perfect.

Purple or dark green.

I's go with black or white or a darker green like someone else said. Does it have the little dots of color in the selvage? They are good for isolating colors.

agree

Aqua maybe?

you dont have to match exact. try a little bit darker. or tone on tones instead of solids. I like the purple

I like the pink and picking up the tanish/yellow color, but to me the green is off, and I would go for something a little darker or with a more blueish tone to it. It's hard to tell on our monitors as each shows color a little differently.

I agree with the black or dark purple...the pink and green would really "POP" :-)

Save some of that wonderful stripe for binding on the bias - what pizzaz that would bring to your finished quilt!
