If you mean the recoil spring guide inside the spring, these are usually blue in color... as a result of heat treatment and tempering... if you mean the L-shaped lever that the mainspring guide attaches to, I think that these are usually white from the factory on guns before 1937 and blue after that, but that is just a guess.
