Question: GuiButton

[Entrok]

This is probably a dumb question, but is it possible to change color on the text on a button?

I have tryed this, but it dident change the color:

new GuiButtonProfile("MerciaButton")
{
  bitmap = mercia_gui-button.png;
  fontcolor = 3,4,7;
  fontsize = 12;
  text = "Test";
}

Would really need to know this, thanks.
