The charts have no contextual understanding of your data, so it is up to
you to tell them what color everything should be. If you change the order
of series, you have to change the options to reflect the new order.
I have never seen the charts ignore the options set, so you will have to
provide an example demonstrating the chart ignoring the colors after you
change the view.
