Hi spacerobot
I'm not sure i understand your question, when you say darken or lighten, what are you referring to? do you mean the "Lightness" in the color shading window, or are you referring to changing all colors to something darker or lighter like the "replace color" tool or maybe the color blend modes which has "Lighten" and "Darken" available or something fourth.
if you can, please rephrase or even better, show an example of what you are trying to achieve :)
