Black & white effect

Hi orianos!

Yes it is. You can add following code to Quick CSS in Enfold theme options under General Styling tab to make images in Logo/partner element have grayscale

#top .avia-logo-element-container img { filter: grayscale(100%);
    -webkit-filter: grayscale(100%); 
    filter: gray;
    -webkit-transition: all .6s ease; }

#top .avia-logo-element-container img:hover {    filter: grayscale(0%);
    -webkit-filter: grayscale(0%);
    filter: none; }

Cheers!

Hi!

Please add following code to Quick CSS as well

.avia-content-slider .slide-image img, .grid-image img { filter: grayscale(100%);
    -webkit-filter: grayscale(100%); 
    filter: gray;
    -webkit-transition: all .6s ease; }

.avia-content-slider .slide-image img:hover, .grid-image img:hover {    filter: grayscale(0%);
    -webkit-filter: grayscale(0%);
    filter: none; }
