title: How to invert text color according to what's behind it? (not only background)
body: <p>All the solutions I have found only work inverting the color of the text element, according to the color of the background. I want the color of the text to be inverted according to whatever is placed behind it (images, videos, 3D models etc.).</p>
  <p>I have some sticky elements in my page, I want their color to change dynamically as the user is scrolling to the inverted color of whatever is displayed behind the text at that moment.</p>
  <p>Thanks.</p>
