Not sure I can really help as I don't do color printing, but in my experience most general purpose developers like XTOL, HC110 etc are neutral, unless you get into certain compensating procedures. A high degree of physical development in non-staining developers can lead to a brownish emulsion color but that happens more with developers like Microdol. For film, not sure if this makes enough of a difference or not, but Delta's film base has a slightly blue-ish cast.
