You can change color via hue-rotate CSS filter. In this example additional class is set to slider and control object is 32/1/2. This will only work in "show control" mode.
Code:
$(function(){
if (typeof grp === 'object') {
grp.listen('32/1/2', function(obj) {
$('.slider').css('filter', 'hue-rotate(' + (obj.value * 3) + 'deg)');
});
}
});
