If your paper tones too quickly, use a weaker dilution. In my experience, dilution does not affect the final image tone, however; it just takes longer to reach with a weaker dilution. Still, using a weaker dilution will give you time to pull the print before it becomes too purple for your taste.

The other option is to use a different paper that tones differently. Choices these days are rather limited, however. I really miss the old Seagull G and how it toned in selenium. The old Ilfobrom (not Galerie) toned beautifully in selenium too, as did Brilliant and even Kodak Elite. All gone now.

We have to work with what we have,
