Dear Tom,
you can try something like this:
t = Table[ {Hue[i/10.0], Disk[{0,0}, 20 i]}, {i, 10, 1, -1} ];
Show[Graphics[t], AspectRatio -> Automatic, PlotRange -> All];
Note that the iteration is downward. That's important, because
otherwise the largest disk is drawn on top of all the others,
obscuring them. It's also important that the fraction i/10 be a real
number.
I'm sure you can figure out how to make this more general than 10
disks or how to add another kind of color function.
