I think you are right that Wall and Jordan is based on that book. What
matters is that there is a good book out there with toning formulas from
1976 or later.

I never tried that toning procedure, but seems interesting. Inproved tonal
range, good long term stability and a subtle colourshift. The four 4-colour
offset illustrations on page 17 showed the split-tone photo under differant
conditions. It works best with a somewhat darker printed print and with a
subject with a medium to high contrast. In this case a man with dark
trousers and a white shirt against a linnen background.

The good thing about Colorvir was the richly illustrated book, which could
be bought seperately.
