You need to use style.map to change the behavior:

pressed_color = 'black'
highlight_color='red'

ttk.Style().map("Treeview.Heading",
                background = [('pressed', '!focus', pressed_color),
                              ('active', highlight_color),
                              ('disabled', '#ffffff')])
