Draw filled TEllipse objects with holes

Dear ROOTers,
in order to be specific, this is a simple example of what I want to achieve (done using GIMP):
c1_hollow_gimp

But I can’t find an easy way of doing it with ROOT. I can either have all circles in gray:
c1_filled
using this code: circle_with_holes.C (1.2 KB)

or all circles transparent (no fill):
c1_hollow
using this code: circle_with_holes_transparent.C (1.2 KB)

Regards,
