Sorry, I deleted your post so I have to respond to it through someone
I believe that the olive green tone you're talking about may have been
created by using lamp black which has a green tone to it. The green can
be accentuated by using the lamp black diluted down with gum until the
green is more evident.
Although lamp black was the black of choice for the 19th century gum
printers, it is generally advised against nowadays. The reason given by
some that it contains pollutants that will degrade the paper was no
doubt true in the 19th century but is not true of modern formulations of
the pigment. Another reason given is that it tends to stain and to
settle out. In the proper concentration for printing I don't find that
it stains, and I like to use to advantage the tendency of the pigment to
sedimentation. So I guess I'd suggest you try it and see what you think.
Anyway, Mac, you will
