Van’s Instant Cold Blue does a very nice job on very clean metal when applied in multiple coats, until the desired color is achieved.
Also claims to work on oily or greasy steel but I prefer to clean the metal thoroughly first.

Brown’s Oxpho-Blue has worked well as far as cold blues go. It doesn’t require a pristine surface, it even goes through a thin film of oil and surface rust not completely cleaned off. I have found it to be the best given it is also available in a cream which stays where you apply it. Follow the directions and you will have good results.
Remember, different steels react differently. That’s why there are different bluing solutions on my shelves. However, rust bluing is so easy and gives great results for big jobs, I only cold blue injuries.

Have found color “takes” more evenly on small parts like sights by heating them up slightly and submerging them in the liquid. Still, even doing it that way doesn’t produce the durability of nitre bluing.
