Hi Luci,

The following is an example of the defintion of an indexed color
function:

ColorDataFunction[10,"Indexed",List[1,11,1],
Function[Part[List[
RGBColor[0.6980392156862745`,0.01568627450980392`,0.`],
RGBColor[0.9215686274509803`,0.49411764705882355`,
0.43137254901960786`],
RGBColor[0.9372549019607843`,0.6274509803921569`,
0.16862745098039217`],
RGBColor[0.9921568627450981`,0.8156862745098039`,
0.49019607843137253`],
RGBColor[0.7254901960784313`,0.8`,0.07058823529411765`],
RGBColor[0.3176470588235294`,0.49019607843137253`,
0.0784313725490196`],
RGBColor[0.17254901960784313`,0.3607843137254902`,
0.07058823529411765`],
RGBColor[0.3607843137254902`,0.40784313725490196`,
0.5333333333333333`],
RGBColor[0.22745098039215686`,0.23921568627450981`,
0.45098039215686275`],
RGBColor[0.09803921568627451`,0.06666666666666667`,
0.25098039215686274`],
RGBColor[0.5607843137254902`,0.5254901960784314`,
0.5647058823529412`]],
Mod[Floor[Slot[1]],11,1]]]]
