There's a big difference between ivory and lamp black. Ivory black is
weaker, more transparent, and slightly warmer. I'm using quinacridone
pigments that are close to magenta in color, e.g. permanent rose. Cobalt
blue and cadmium yellow. Yes, cobalt blue is weak (in powder form) but it's
beautiful and prints nicely.
The "light pigment" thread illustrates one of the strengths of gum - the
great degree of control the process allows and the wide range of results
possible. I print most of my gums with deep, rich tones and strong
contrast. I'll have some of my work up on a website in the near future.
I'll post the URL when available.
Best regards,
