Hola, MITOPE.

Prueba este código a ver si te sirve

procedure TForm1.DBGrid1DrawColumnCell(Sender: TObject; const Rect: TRect;
  DataCol: Integer; Column: TColumn; State: TGridDrawState);
var
  Num: Integer;
  R: TRect;
begin
  Num:=TStringGrid(DBGrid1).Row;
  R:=TStringGrid(DBGrid1).CellRect(DataCol,Num);
  if R.Top=Rect.Top then
    with DBGrid1 do
    begin
      if (gdFocused in State) then
        Canvas.Font.Color:=clWhite
      else
        Canvas.Font.Color:=clRed;
      Canvas.Font.Style:=[fsBold];
      DefaultDrawColumnCell(Rect,DataCol,Column,State);
    end;
end

Saludos,
