Marbling "inks" as people insist on calling them, are really paint,
technically speaking, being pigment based. But people like to call them
inks, so I accept either term when speaking to people.....after all we are
talking about the same substance! It's just easier.
When I used gouache years ago, I diluted the tube with 1 -2 cups of water.
My own colors (to avoid the use of the terms paint or inks!) need no
dilution, unless someone wants to use them thinner. Generally they are
ready as-is. Colophon's colors, at least when Don was making them (I don't
know if Nancy is using the same formulations, but I believe she is), come
as a concentrate, and there should be directions on the jar. Basically, one
thins them to the consistency they like.
One big mistake people make is thinking that a thicker denser paint will
give a brighter color. Not so , because, remember you are dealing with an
important physical property.....specific gravity. The drops of paint must
be LIGHTER in weight than the bath, or they will sink. The cadmiums, reds
in particular (and yellow & orange to a lesser degree) are lead-based (not
dangerous in the liquid form, but a danger when making the paint and
breathing the pigment powders), and have a high specific gravity. That is
why many people have the most trouble with reds. They use them densely,
thinking they will get a deep red, but by the time they lay the paper, some
of the color has started to sink a hair below the size surface and they
come up with a dull liver color red. So with reds, proper dilution is
extra-necessary. Adding a little more water in this case, gives a better
So, to answer the question.....dilution of each color may be an individual
process for each of them. Experiment until it works for you.
