Line Color

ROOT

I need to draw a line in different color using TVirtualX->DrawLine(). Seeing the reference, I saw the SetLineColor(Color_t cindex), and I hope it will work for this. But what exactly is the parameter that go inside the function? How can I specify another color?

Thank you very much!
