You can change the icon (though not the color) in the element information window via the Set icon button. The default Fire station element is orange. If you have a red icon you prefer, you may also select it. To change the icon for a set of fire stations, start in the Manage content window, select those elements from the list, then click view/edit to get to the info window.

Let us know if that doesn't work for you.
Happy Depicting!
