You are not starting the animation anywhere. Either start it by calling start(), or use the declarative approach. Here's an example for the former:

ProgressBar{
  id : p1
  indeterminate: true
  onValueChanged: anim.start()
  ColorAnimation {
    id: anim
    from: "white"
    to: "black"
    duration: 200
  }
}
