maybe just the lighting, but there should be no layers of pink in the OEM paint system on a blue car, if you really see pink under there, that would indicate a previous repair and that would be why the paint may have come off.
Also - if you want to admire your beautiful paint, stop going to the car wash as they make your paint much less beautiful!
