    How to Change Value and Color on an Isosurface
    //var voxelLayer = ... ;
    //Must be on the QueuedTask.Run()
    var variable = voxelLayer.SelectedVariableProfile;
    //Change the color of the first surface for the given profile
    var surface = variable.GetIsosurfaces().FirstOrDefault();
    if (surface != null)
        if (voxelLayer.Visualization != VoxelVisualization.Surface)
        //Change the iso surface voxel value
        surface.Value = surface.Value * 0.9;
        //get a random color
        var count = new Random().Next(0, 100);
        var colors = ColorFactory.Instance.GenerateColorsFromColorRamp(
            ((CIMVoxelStretchRenderer)variable.Renderer).ColorRamp, count);
        var idx = new Random().Next(0, count - 1);
        surface.Color = colors[idx];
        //set the custom color flag true to lock the color
        //locking the color prevents it from being changed if the
        //renderer color range or color theme is updated
        surface.IsCustomColor = true;
        //update the surface
