How to draw font colors for drop-down options independently in Winform ComboBox

As we all know, the font color will be changed and drop-down options at the same time.

Independently draw the drop-down option font color, ForeColor is only effective for colors, example:

private void cb7_DrawItem(object sender, DrawItemEventArgs e)
{
  DrawCboItems(sender, e);
}

private void cb7_SelectedIndexChanged(object sender, EventArgs e)
{
  SetCboTextColor(sender);
}

private void SetCboTextColor(object sender)
{
  ComboBox cbx = sender as ComboBox;
  if ( == "+")
     = ;
  else
     = ;
}

private void DrawCboItems(object sender, DrawItemEventArgs e)
{
  ComboBox cbo = sender as ComboBox;

  //Initialize the font and background color  Pen fColor = new Pen();
  Pen bColor = new Pen();

  switch ()
  { //Index of drop-down options  case 1:
  {
    fColor = new Pen();
    break;
  }
  }

  (, );
  ((string)[], , , );
}
