Change mask color on slideshow

I have purchased JA-Lawfirm. I need to modify the masking on the slideshow to a lighter gray. How do I do that?

It's opacity of slideshow image, you can override by this custom css rule:

.slideshow .img-bg {
    opacity: 1 !important; }

put this code into the file: /templates/ja_lawfirm/css/custom.css (Create this file if it doesn't exist)

Regards
