What color shoes.....? - what color shoes with a gray tuxedo

My brother got married and I am the maid of honor. The colors are yellow and gray. My brother used, such as ivory, all ex. Jacket, shirt, pants, shoes, jacket, etc.. The groomsmen wore gray suits. Servants of the bride are yellow. But the problem is that I do not know what color I should wear shoes. It is to decide for us and buy our own shoes. It is silver or gold or yellow.
I need help:) What color shoes would go perfectly with this?
