.image-container .after {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    display: none;
    color: #FFF;
}
.image-container:hover .after {
    display: block;
    transition:all 0.2s ease;
    background: rgba(0, 0, 0, .6);
}

Other solution is that useing CSS filter.such as Filter Functions .
Exmple:

CSS:

 img { display: block; width: 90%; }

    img {
      -webkit-filter: sepia(1);
      filter: sepia(1);
    }  

and result:Filter Functions
