the great mat debate

Here is the problem: blank wall, in master bathroom




Here is the solution: a photo I took and had blown up.
However, I have another problem: Should I use the black mat or the white one? (bathroom fixtures are brushed nickel and the mirror has a wide frame - black with a silver decorative design overlay. I also have hanging - a very small, square framed cross/Bible verse that has a black background, white mat and silver frame). The leaves in this photo are inspired by the painting above our bed, which is a fall, tree scene painted on canvas.

Opinions??
