How to change TAdvGlowButton font color at runtime?

I try to set TAdvGlowButton caption font color at run time:

Btn1.Font.Color := clRed;

But the font color is still clWindowFont (Default). I tried to do it with UseAppearance True and False.
The font style can be changed it RunTIme (Btn1.Font.Style := [fsBold]);
Font color can be changed at design time.
The notes font color can be changed at run time.
I called Repaint after setting the font, but no effect.
Should I change some settings? (TMS VCL UI Pack, Delphi 11, Windows 11)

This example changes the button font:

procedure TForm1.Button1Click(Sender: TObject);
  advglowbutton1.Font.Name := 'Courier New';
  advglowbutton1.Font.Color := clRed;
  advglowbutton1.Appearance.SystemFont := false;

Thank you for quick answer.
I set it:
Btn.Font.Name := 'Courier New';
Btn.Font.Color := clRed;
Btn.Appearance.SystemFont := False;
Btn.NotesFont.Color := clRed;
Btn.Caption := BadName;
Btn.Notes.Text := Notes;
Btn.Font.Style := FStyle;

But the Caption remains black:


What are the other component settings?
With a default TAdvGlowButton on the form, this works.

I have got it. The feature Appearance.TextColor, not visible in the designer, is more important than Font.Color. If you set:
Btn.Appearance.TextColor := clBlack;
Btn.Appearance.SystemFont := False;
then Font.Color has not meaning.
Thank you for cooperation and help!
