Hola Yo de nuevo,
He buscado en la Red y he encontrado esta dirección:

El código funciona bien para un CheckBox, Label, StaticText, pero no así en un TButton, TTabSheet, donde apunto mi pregunta, ¿Que implementación requiere dicho ejemplo para cambiar el color de la propiedad HotTrack en un TTabSheet?

Código Delphi [-]
procedure TForm1.WndProc(var Mesg : TMessage) ;
begin
{ Here we see which component gets changed. 
  This bit here tells us which
  component the mouse is over }
     if Mesg.LParam = Longint(Label1) then
        ChangeColor(Label1, Mesg.Msg) ;
     if Mesg.LParam = Longint(Label2) then
        ChangeColor(Label2, Mesg.Msg) ;
     if Mesg.LParam = Longint(Label3) then
        ChangeColor(Label3, Mesg.Msg) ;
     if Mesg.LParam = Longint(CheckBox1) then
        ChangeColor(CheckBox1, Mesg.Msg) ;
   inherited WndProc(Mesg) ;
end;
procedure TForm1.ChangeColor
   (Sender : TObject; Msg : Integer) ;
Begin
{ If a label is the one that the mouse
is over then we do this } 
  if Sender IS TLabel Then
   begin
     if (Msg = CM_MOUSELEAVE) then
      (Sender As TLabel).Font.Color:=clWindowText;
     if (Msg = CM_MOUSEENTER) then
      (Sender As TLabel).Font.Color:=clBlue;
   end;
{ If a CheckBox is the one ... } 
  if Sender IS TCheckBox Then
   begin
    if (Msg = CM_MOUSELEAVE) then
     (Sender As TCheckBox).Font.Color:=clWindowText ;
    if (Msg = CM_MOUSEENTER) then
     (Sender As TCheckBox).Font.Color:=clRed ;
   end;
end;
