Hi Adam,
//example of new colors (greys) and definition of a new palette
void palette() {
const Int_t colNum = 100;
Int_t palette[colNum];
for (Int_t i=0;i<colNum;i++) {
TColor *color = new TColor(501+i
,1-Float_t(i)/colNum
,1-Float_t(i)/colNum
,1-Float_t(i)/colNum,"");
palette[i] = 501+i;
}
gStyle->SetPalette(colNum,palette);
TF2 *f2 = new TF2("f2","exp(-(x^2) - (y^2))",-1.5,1.5,-1.5,1.5);
f2->SetContour(colNum);
f2->Draw("contz");
}
