While [NSCell backgroundStyle] works well for highlighted/unhighlighted, it doesn't seem to work for when the window isn't key/focused. @ken Only tried this just now.

Set the template image on the button cell. Override setBackgroundStyle: to forward it to the button cell. Override drawInterior to draw the button cell in addition to calling super. Override -trackMouse:inRect:ofView:untilMouseUp: to forward tracking to the button cell when the initial mouse down is over the button. Let the button cell handle all the work, just forward appropriate methods to it. Basically, try having your cell have an NSButtonCell as an instance. Set the template image on the button cell.

The image is supplied by the framework - see NSImageNameFollowLinkFreestandingTemplate. The effects can also be done automatically provided you draw a cell rather than the image directly and propagate background styles correctly. See http://developer.apple.com/mac/library/releasenotes/cocoa/AppKitOlderNotes.html#TextAndImageEffects for details. You shouldn’t need quite this much work.
