I use M. Graham pigments and for gum overs I've been working with:
Since I work with very thin layers of gum I've never been quite happy with one layer of gum as I perfer a stronger color rendering. And yes I've had a lot of failures but I just file them away.
I'm also thinking of trying Quinacridone Rose or Violet in a mix for an effect in the darker tones. There are just too many choices.
