About a quarter of the way down the stylesheet (style.css) you’ll find this:
/* slider Begin */
#zSlider{margin-bottom:20px;}
#zSlider .description{list-style:none;width:100%;margin:0;}
#zSlider .description li{width:25%;float:left;margin:0;cursor:pointer;background:rgba(87,87,87,0.8);filter: progid:DXImageTransform.Microsoft.gradient(startcolorstr=#cd575757,endcolorstr=#cd575757);}
#zSlider .description li.active{background:rgba(87,87,87,0.5);filter: progid:DXImageTransform.Microsoft.gradient(startcolorstr=#7f575757,endcolorstr=#7f575757);}
#zSlider .description li.over{background:rgba(87,87,87,0.65);filter: progid:DXImageTransform.Microsoft.gradient(startcolorstr=#a6575757,endcolorstr=#a6575757);}
#zSlider .description strong{display:block;margin:20px 15px 15px;color:#aeaead;font-size:20px;}
#zSlider .description li.active strong{color:#325C74;}
#zSlider .description li.over strong{color:#889f70;}
#zSlider .description p{margin:10px 15px;color:#dddddd;}
#zSlider .description li.active p{margin:10px 15px;color:#a7a7a7;}
/* slider End */
So you can squirrel around with the colors here, for the background color the selectors seem to be:
#zSlider .description li
#zSlider .description li.active
#zSlider .description li.over
#zSlider .description li.active strong
#zSlider .description li.over strong
And for the text it seems to be:
#zSlider .description p
#zSlider .description li.active p
Hope this helps!
