My first inclination would be something like this:

colors = {Blue, Red, Purple, Plum, Gold, Olive,
Pink, Navy, Mint, Black};

Show[Graphics[Table[{colors[[i]], Disk[{0, 0}, 220
- 20 i]}, {i, 1, 10}]], 
  AspectRatio -> Automatic, PlotRange -> All];

and if you didn't care about the colors, something
like this:

Graphics[Table[{RGBColor[1 - i/10, i/10, 1 -
i/20], 
        Disk[{0, 0}, 220 - 20 i]}, {i, 1, 10}]],
AspectRatio -> Automatic, 
  PlotRange -> All];

Ooo... pretty.
