You're right Gini. Probably the reason I didn't think to mention amount
of pigment was because
my personal struggle is usually in the opposite direction -- a
tendency (no doubt caught from my students) to pile on so much pigment
that the print loses translucency and delicacy. Also, too much pigment
can be a source of flaking (because it has its own gum content) and
staining (the gum will suspend just so much pigment) if
those bother you. (I hate it when somebody's nose flakes off!)
I suspect, too that you can get away with denser pigment in tri-color,
where the coats aren't exact duplicates, than with monochrome, where
the next coat and all other nexts are likely to go right in the same
places. Anyway, you do make tri-color sound inviting ......
