I don't recall the color, red maybe? Regardless, I think someone got it in the wrong spots when they installed the sights at the factory. It was probably just an anomaly with my gun, but it was incredibly annoying until I figured out what was causing the problem.
Before you start tweaking the sights, I'd shoot it from a bench and see how the gun is shooting. I was having the same problem shooting low and left when I got mine and it turned out that it took me a while to adjust to the grip and bore axis. I've also talked to a couple of other P226 owners that went through a similar adjustment period.
