There's no way for us to really know what is a good idea, colour wise, or style wise for your border and binding ... being that we have not seen your quilt. Plus, what one likes, another will not. It's your quilt ... and you will know what you like or don't like!
The best way is to "audition" possibilities against your finished quilt top.
If you need inspiration, start with the pics in the Gallery photos here on the QB. There are so many possiblities beyond basic black and white ... and flat plain border strips.
And too, not all quilts "demand" borders. The quilt may be enough, and then just a binding along the outer edge.
