Chuck,
I had spoken with Dr. Gaddy a number of times on this subject. Some of his tests showed that good colors can be achieved at very low temperatures. The low temps must not affect the hardness of the already heat treated steel. I would guess that is how Turnbull colors any modern actions or cast actions such as Rugers, but who knows. Either way, I say buy one that is colored, much easier and safer. I also dont know how they would "paint" those colors on, but hey who knows nowadays. They sure look like authentic case colors in the pictures.
