Hey Johnson. Thx! I used the fuzzy tip with pressure sensivity on while opacity is set on 85%. Color was black or very dark grey. I usually calibrate my Colors! with very light pressure sensivity, so I don't need to push very hard. But the trick is fuzzy tip with very small diameter (try 5 to 6 pixel above the bottom of the scale). Simulates a pencil very good. And I like to draw at zoomlevel 2x.
Oh, and I forget to say that I got best results by using a real pencil instead of the stylus. Sounds ridiculous I know ;) Don't worry, it won't scratch the surface or leave traces.
