How do I colour 'SliderPack' sliders by index??

[Chazrox]

Im trying to color my sliders by index. I've traced the slider pack to get all properties and i've found this but I cant seem to access it...

I wanna do something like this...

		if (SliderPack3.get("displayIndex") == 3)
		{
			g.fillAll(Colours.red);
		}

also found these.....

laf.registerFunction("drawLinearSlider", function(g, obj)
{
	if (obj.id == 3)
	{
		g.fillAll(Colours.red);
	}
});
