Okay, now that I have read a little, I think I understand the Istari more.
Since I cannot just post a link because the whole site uses the same address, I'll quote it. Here's what they said about the Blue Wizards in general:
The two Wizards, Alatar and Pallando, who did not remain in the west of Middle-earth, but journeyed into its far eastern regions.
They said more when I clicked on the profile for Alatar.
One of the five Wizards who came to the northwest of Middle-earth in the Third Age; he journeyed into the east with Pallando, and never returned to the western lands. Alatar was one of the original three Wizards selected by the Valar for the journey from Valinor to Middle-earth (the other two being Curumo and Olórin - Saruman and Gandalf). Alatar and Pallando arrived in Middle-earth dressed in sea-blue. For this reason, they were together given the name Ithryn Luin, the Blue Wizards. With Saruman, they journeyed into the far east of Middle-earth, but while Saruman returned to the west, Alatar and Pallando did not. Of their fate, we know almost nothing.
What I also find interesting is that they take notes and use speculation and things Tolkien has said, as well as translation for names. One note is that Alatar and Pallando were not well known to men, thus they never gained names like Gandalf, Saruman, and Radagast had. Their names are more like meanings. Alatar roughly translates to 'after-comer' and Pallando roughly to 'far-traveling one'.
Another note they stated was something Tolkien had said.
Tolkien tells us 'What success they [Alatar and Pallando] had I do not know; but I fear they failed, as Saruman did, though doubtless in different ways; and I suspect they were the founders or beginners of secret cults and 'magic' traditions that outlasted the fall of Sauron.' (The Letters of J.R.R. Tolkien, No. 211).
I also learned that the Valar were going to just send three Istari - Saruman, Gandalf, and Alatar - to Middle-Earth, but the Vala Yavanna added Radagast and Pallando was taken along as Alatar's friend.
