Change Payment Icons - Broadcast Theme

[jzcreativespace]

Hi! I was wondering if it is possible to change the icon style of the payment icons. I would like them to just be icons, preferably black icon with white background. I attached photos of how they look now vs. the style I would like them to be (but colors reversed). I am using the Broadcast Theme in the Clean style. Thanks!
