Thanks Charles! Looks very interesting, but I'm not able to use it yet: what does it need as input layer(s)/features?
Does it need a count column? This is only setting the color of overlapping features yes?

Meanwhile I found
https://github.com/kgjenkins/qgis-count-polygon-overlap

Which happily counts the overlaps, after using my earlier expression to create the different polygons, so I can easily color them according to that count. See screenshot.

I'm still very interested in your coloring expression though :-)
