I see there are some mesbg enthusiasts here, so I figure this is a good opportunity to ask some people who are hopefully better versed in the more obscure details of the lore and could point me in the right direction.
I've been wondering if there were any more definitive or "official" (as in it was approved by the Tolkien estate at least, if not written or drawn by the man himself) descriptions or maybe even illustrations for the Blue Wizards than the vague "not as old as Gandalf and wearing sea-blue robes" in addition to Saruman's reference to all wizards having staves. That seems to be the extend of the information that exists, really. Some other adaption made inferences about them, but the most fleshed out version seems to be from the 1993 RPG. One was represented as a skilled hunter using and elven bow and the other as being able to trap souls, like a TES protagonist. Not sure if that is based on anything of substance though.

The closest I've come to something that must have at least went through some sort of approval process was this image from an item in the Shadow of War videogame. Outside of that I didn't have much luck, even finding illustrations from John Howe or other people commonly associated with Tolkiens work. There are a lot of illustrations, but even if they are referenced on a wiki they are not usually cited with a source or any additional information.

I thought converting and painting some Blue Wizard minis might be a fun modelling project, but I kind of went down a rabbit hole with this one it seems.
