Sorry I didn't make myself more transparent here. I meant that to me,
any pigment that's not absolutely transparent will have some of that
veil-like quality, even with the added gum and the thinness of the
layer. The extra gum doesn't make the pigment more transparent, it
simply spreads the less transparent pigment particles farther apart, so
to me there's always a bit of a haze there, though faint. I want my
multiple gums to glow with luscious luminous jewel-like colors; anything
that puts even the slightest haze over the luminosity is objectionable
to me. At the same time, I recognize that not everyone is as particular
about transparency as I am. My point was that pigments are unique, and
it doesn't make sense to me to say that a semi-transparent pigment is
interchangeable with a transparent one, since to my eye they aren't.
Cheers,
Katharine
