How do I make the "menu icon" change color to dark when it's on a white background and vice versa?

I need the menu icon to change its color to dark or white, depending on what background it is on. And I must say right away that this is code. This is not done in Muse and not a widget. https://codepen.io/RSH87/pen/rmgYbo (this)
