I have not been able to figure out yet how LabelBox line color is changed...

here are some examples I figured out how to do it:

struct sChLook_LabelBox {
	Image img;
};

Value Make_ChLook_LabelBox(const Image& img)
{
	sChLook_LabelBox x;
	x.img = MakeButton(8, img, 1, SBlack());
	return RawToValue(x);
}

Value ChLookFn_LabelBox(Draw& w, const Rect& r, const Value& v, int op, Color ink) {
	
	if( v.Is<sChLook_LabelBox>() )
	{
		const sChLook_LabelBox& e = v.To<sChLook_LabelBox>();
		ChPaint(w, r, e.img);
		return 1;
	}
	return Null;
}

INITBLOCK {
	ChLookFn(ChLookFn_LabelBox);
}

GUI_APP_MAIN
{
	LabelBox::SetLook(White());
	LabelBox::SetLook(WithHotSpots(MakeButton(8, MyImg::BACKGND1(), 5, Blue()), DPI(8), DPI(8), 0, 0));
	LabelBox::SetLook( MakeButton(4, MyImg::BACKGND1(), 2, Null) );

	
	static const Value myLabelBoxLook = Make_ChLook_LabelBox(MyImg::BACKGND2);
	LabelBox::SetLook( myLabelBoxLook );

        .....
}
