How to get the ttk Button background color?
<p>I want to programmatically find out what color is being used for the background color of a tkinter <code>ttk.Button</code>. To be clear, I'm not trying to set or change the background color (since that cannot be done), merely get the color so I can use that color elsewhere. The standard process of <code>cget('background')</code> will not work for a ttk button, so how else might I get the button background color?</p>

<p>Note, this answer needs to be system independent.</p>
