ok.

In fact I love those colorschemes.
What I was trying to explain is that if the grouping is by bins, then,
just to do a simple example:

I have a shapefile with all the parishes of Italy. About 1000 and some
more. Let's say I have just an ID attribute and the IDs were taken from
north to south. Now I want to render them, showing them all different.
With the actual approach it takes the first 80 and colors them the same
way and so on. The result is a map of Italy in stripes, instead of an
arlecchino as I wanted to.
