title: change css background-image svg paint behavior on hover?
body: <p>I am using an svg as a background image for a button.</p>
  
  <p>The button needs different hover states, which are just changes to the svg fill values.</p>
  
  <p>Is there a clever way to make these changes to the svg which is effectively just being used as an image, or do I need to create a different svg file with a different fill color?</p>
