I am using a "spinner" NSProgressIndicator in my cocoa app:

I would like to display it in a different color so that it will show up well on a dark background:

How would I go about doing this? My last resort would be to write my own custom NSView subclass that renders a custom animation, but I'm not even sure where to start on that front. Any help is appreciated.
