Varies with developer. I am currently processing it in Legacy Pro Eco Pro, an ascorbic-based developer, which gives the "hint of warmth without green" that I've come to prefer. In Neutol NE it's fairly neutral. I've used Moersch SE-6 to cool Multigrade FB Warmtone so it's completely neutral. Haven't tried SE-6 on Galerie, but would go there next if seeking neutral-to-cool images.
I haven't tried any of those, and they don't seem to be available in my location. I have heard of Moersch, so I might look into ordering some. Thanks for the information!
