Regarding the Blue Wizards:

Of the Blue little was known in the West, and they had no names save Ithryn Luin "the Blue Wizards;" for they passed into the East with Curunír, but they never returned, and whether they remained in the East, pursuing there the purposes for which they were sent; or perished; or as some hold were ensnared by Sauron and became his servants, is not now known. 3 But none of these chances were impossible to be; for, strange indeed though this may seem, the Istari, being clad in bodies of Middle-earth, might even as Men and Elves fall away from their purposes. and do evil, forgetting the good in the search for power to effect it.

Whereas in the essay on the Istari it is said that the two who passed into the East had no names save Ithryn Luin "the Blue Wizards" (meaning of course that they had no names in the West of Middle-earth), here they are named, as Alatar and Pallando, and are associated with Oromë, though no hint is given of the reason for this relationship. It might be (though this is the merest guess) that Oromë of all Valar had the greatest knowledge of the further parts of Middle-earth, and that the Blue Wizards were destined to journey in those regions and to remain there.
