Needs["Graphics`Colors`"];

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

nmax = Length[colorList];

Show[Graphics[
      Table[{colorList[[n]], Disk[{0, 0}, 20(nmax - n + 1)]}, {n, nmax}]], 
    AspectRatio -> 1];

or equivalently,

Show[Graphics[{colorList[[#]], Disk[{0, 0}, 20(nmax - # + 1)]} & /@ 
        Range[nmax]], AspectRatio -> 1];

If a list of specific colors is not required, then use a color function:

Show[Graphics[
      Table[{Hue[2(nmax - n)/(nmax - 1)], 
          Disk[{0, 0}, 20(nmax - n + 1)]}, {n, nmax}]], AspectRatio -> 1];
