I need help I tried doing what I did and background-blend-mode: exclusion; but it doesn't work.

style.css 
main {
  max-width: 600px;
  height: 400px;
  background: url(mtn-landscape.jpg) center / cover mediumaquamarine;
  /* Add blend mode here */
  background-blend-mode: hard-light ;
}

Neither hard-light nor exclusion modes conform to the challenge instructions. The challenge says: "Use the value that multiplies background-image and background-color to create a darker background."

Hint: Note that the description contains a word that should help identify the correct blending mode.   :wink:
