Why don't just convert the NSColor to CGColor?
CGFloat colorComponents[4];
[[NSColor redColor]
colorUsingColorSpaceName:NSDeviceRGBColorSpace] getComponents:colorComponents];
// Create the CGColor
CGColorRef myCGColor =
(id)CGColorCreateGenericRGB(
colorComponents[0],
colorComponents[1],
colorComponents[2],
colorComponents[3])
;
