This is usually done by assigning an empty string to a property, e.g.:

element.style.backgroundColor = '';

As far as `removeStyle` helper, something like this should work:

Element.addMethods({
  removeStyle: function(element) {
    element = $(element);
    $A(arguments).slice(1).each(function(style) {
      element.setStyle({ style: '' })
    });
    return element;
  }

});

// then

$(someElement).removeStyle('color', 'opacity', 'position');
