Hi Adrian,
a version of "Pos" coloring that behaves as you have described is
currently in the planning stages and should be included with a future
release, but isn't currently available. If you'd like to have this
coloring now, you should probably figure out what you want your coloring
function to be and map it to the beta field (let me know if this doesn't
make sense).

As far as color bands, please check out the color scale bar plugin
( and
remember that you can tweak the color scale data range under the
Trajectory tab of the graphical reps menu.
