ColorAnimation does not support easing?

[h00bs]

Is it possible that ColorAnimation type does not support easing? I can't find anything about it in the docs or on the web, but when I try something like this:

Rectangle {
  id: background
  anchors.fill: parent
  color: "#162d40"
  ColorAnimation on color {
    loops: Animation.Infinite
    easing.type: Easing.SineCurve
    running: true
    from: "#162d40"
    to: "#255c89"
    duration: 3000
  }
}

I always get an error "Property assignment expected" in the line with the easing.

Best Regards,
Alex
