~ Pick a Binding, any Binding ~

I am just about finished with the machine quilting on my Bucket List quilt.

I stitched waves on the sea fabric.

And swirls on the sand fabric.

I put swirls on the buckets that hold sand, and waves on the buckets that hold water.
I don't know why I insist on being so literal, but let's face it, I'm too old at this point to change.

I have a plan in my head to quilt on the pinwheel/solid border, but I couldn't decide which of the thread colors to use.  Then it occured to me to use the same color of whatever fabric I picked for the binding.
Except ... I can't seem to make that decision, either.

So I am asking you.  You tell me which of the above three fabrics (green, orange, pink) I should use for the binding and hence ... the color of the thread to machine quilt the border. 
I ruled out the yellow, the sea fabric and the sand fabric because I don't have enough of either of those.
I also have enough of the pink stripe ... so you can add that to the mix.
So hurry and vote already since I have dragged my feet far too long on this quilt as it is.  I pretty much blame that on summer.

Pink or Green or Orange?
