I think Yume's color should Hime's (if that is her name and not one of the others) and Yume should have a brighter pink. Their colors look a bit too similar where they are now and that would make Hime's color easier to see on the white of the wiki. Jo has the final decision on the actual hex codes, but as the one who's done most of the color coding on the first wiki, that's just my two cents.

And to address your concern, I don't think it matters whether or not it clashes with Madoka's color since their songs will be on separate wikis anyway.
