Dragging Image

I have an NSTableView subclass that overrides the dragging image:

- (NSImage *)dragImageForRows:(NSArray *)dragRows event:(NSEvent
*)dragEvent dragImageOffset:(NSPointPointer)dragImageOffset
{
NSImage* image = [super dragImageForRows: dragRows event: dragEvent
dragImageOffset: dragImageOffset];

NSImage* imageProper = [[NSImage alloc] initWithSize: [image size]];

[imageProper lockFocus];
[[[NSColor selectedControlColor] colorWithAlphaComponent: 0.5]
set];
NSRect fillRect = NSMakeRect(0, 0, 0, 0);
fillRect.size = [imageProper size];
[NSBezierPath fillRect: fillRect];
[image dissolveToPoint: NSMakePoint(0, 0) fraction: 1.0];
[imageProper unlockFocus];

return imageProper;
}

The result is a translucent blue rectangle with black text.

How do I invert the text to make it white? Thanks.
