I posted a question on this a while back and I never got a really good answer, it seems mathematica was not designed for extreme ease in plotting data points that are scattered. I believe I ended up doing it with Hue[z/maxz*.9]. The .9 is because with Hue[z], both z=0 and z=1 are red. I'm currently running to the same problem with contours, my max and min heights are red if I want color, or I can remain in grayscale.
