Background image clip-path color

Hey, I was wondering if there is a way to change the clip-path shape’s color. Or change the opacity. Here is my code so far.

// Header Section
.header {
  padding: 1.6em; // 16px/10px = 2em
  &__container {
    background-attachment: fixed;
    background-size: cover;
    background-repeat: no-repeat;
    background-position: center;
    background-image: url(https://i.imgur.com/Txm2nfS.jpg);
    height: 100vh;
    clip-path: polygon(0 0, 95% 0, 100% 10%, 100% 100%, 5% 100%, 0 90%);
  }
}

Hi,

Have you tried opacity or background-color properties?
