This worked for me: NSColor* browserBackgroundColor = [NSColor colorWithCalibratedWhite:0.10 alpha:0.60];
[_effectsBrowser setValue:browserBackgroundColor forKey:IKImageBrowserBackgroundColorKey]; Are you sure that it's not working for you? Perhaps a superview has a non-transparent background itself and that's what you're seeing?
