I think it's just in the brand, and the color don't mean much, its just what I have. I use a pretty thin version of this, similar to what they put on car door hinges, thats non-drying, or it seems to not. I'm not sure what the base grease is, they just add the Moly to it, but it is thin. Mine came in a small tube, about two ounces or so. Anyhow, the thinner the better, just as long as it will adhere to the linkage, and in the hammer safety slot in the frame. It seems to make them slide a lot freer and lubricate longer than with oil.
Everything else, though, runs on pivots, so a drop of oil on each is enough on it.
