Fixed symbol color on latitude-longitude maps

Hello, I'm using a latitude-longitude map chart type to display my different programs across the U.S. map. Each program is automatically assigned their unique color for the plot point (which is fine) but when I filter the data to show single program data, the plot point color changes automatically (from green to red).

Is there a way to keep the color fixed so that it doesn't automatically change when a filter is applied?

Thanks in advance!
