Changing color Halo in unity 5 (Scripting)

Hi,

I've seen this question asked before, but I cannot find the color change value of the Halo. When I asked the properties of the halo in the gameObject, i don't see any color data that can be changed.

      Component PointHalo = PointHaloSmall.GetComponent("Halo");
      _PropertyInfo[] properties =   PointHalo.GetType().GetProperties();
      foreach( _PropertyInfo p in properties)
     {
        Debug.Log(p.Name);
     }
