It's probably because of the fancy triple-layer paint used to make Soul Red, but this touch up paint I bought from Mazda is the poorest matching OEM touch up paint I've ever used, and I've used quite a few over the years. It's significantly lighter in color than the factory paint, to the point where I think it might look worse than leaving the scratch or stone chip unpainted. That's probably an overstatement, but it's a pretty bad match. I made sure to shake up the tube well, too.
