Hi Dennis,
Generally, you'll use TF1::SetLineColor . For example:
TF1 *myfunc = new TF1("myfunc","[0]*sin(x)/x",0,10);
myfunc->SetLineColor(2); // sets the color to red
Or, if you are doing a fit with a standard function:
h->Fit("gaus");
h->GetFunction("gaus")->SetLineColor(3);
Similarly, you have access to SetLineStyle, etc...
Good luck,
Rob
