begin
with ARichEdit do
begin
SelStart := Length(Text);
SelAttributes.Color := AColor;
SelAttributes.Size := 8;
SelAttributes.Name := 'MS Sans Serif';
Lines.Add(AText);
end;
end;
procedure TForm1.Button1Click(Sender: TObject);

procedure RE_ColorLine(ARichEdit: TRichEdit; ARow: Integer; AColor: TColor);
begin
with ARichEdit do
begin
SelStart := SendMessage(Handle, EM_LINEINDEX, ARow - 1, 0);
SelLength := Length(Lines[ARow - 1]);
SelAttributes.Color := AColor;
