Background Color

I am using the black skin for the mini audio player, which causes their to be a black box behind the player and around the download button. Is there anyway to change that color to white (#fff), so in blends in with the background of the website and makes the player look more natural? I don’t want to change the colors of the skin itself, just the box that the player sits on top of.

Thanks.
