While I was editing one of the transcripts a long time ago, Monty mentioned that there were a lot of lucky coincidences while finding a character that their owns characters could be inspired from, and Weiss had a lot of 'white' stories they've drawn stuff from. (He also said that other characters had stories that were related to their color.)

That means Weiss' main inspiration is likely Snow White, but she's also somewhat inspired from other 'White' characters. If Weiss was inspired by multiple stories, then it's likely the other characters were, too, like Ruby being Rose-Red.

By the way, thanks for noting the white cloaked person in 'Snow-White and Rose-Red'. I might have read about it before, but I completely missed that part. (Then again, White Cloak wasn't around at the time. XD)
