Hello, Antti,

   Thank you for your input! The built-in definition for ColorData[1] happe=
ns
to be

ColorDataFunction[1, "Indexed", {1, Infinity, 1},
 (ToColor[Hue[N[FractionalPart[0.67 + (2*(#1 - 1))/GoldenRatio]], 0.6,
      0.6], RGBColor] & )[Floor[#1 - 1, 1] + 1] & ]

  I guess I should have just investigated that earlier. Now I know how.

              Thanks again,
                            C.O.
