I've never used gold toner, and have been told that I might use it for blue tones on certain papers. Any tips, before I spent any future inheritences on it? I typically use Ilford and Forte Elegance fiber papers.

I should add that what I'm looking for is a pronounced blue toner that is more subtle than what I have been able to get from Berg blue toner (greatly diluted.) If toners other than gold would work for this purpose, I'd love to hear about them.

Thanks in advance.
