I have the color table blues :(

Does anyone have any tips on how to make a discrete set of 25 colors
into a continuous 255 element color table?  The discrete colors are:

  rgb = [[153,153,153], $
         [212,170,255], $
         [178,102,255], $
         [127,  0,255], $
         [102,140,255], $
         [  0, 63,255], $
         [  0,127,127], $
         [102,197,255], $
         [102,255,197], $
         [  0,255,159], $
         [ 31,255,  0], $
         [ 63,127,  0], $
         [178,255,102], $
         [212,255,170], $
         [223,255,  0], $
         [255,216,102], $
         [255,143, 76], $
         [191,  0,  0], $
         [255,  0, 95], $
         [255,102,159], $
         [116, 38,127], $
         [127,  0,  0], $
         [127, 76, 51], $
         [127, 47,  0], $
         [ 76, 61, 61]]

I'd like them to transition 'smoothly' from one to the next but I'm
not sure what the best way to do this is.

Thanks.

 CONGRID, with the INTERP keyword set. :-)
