Hello
It is possible with some CSS. Take note that for the following CSS the first slide is
0, the second
1, the third
2 and so on...
This would be for the third slide (edit taste)...
[data-slick-index="2"] .layerslideshow-title {
color: #999999;
}
The easiest option would be to set the most common color in your module settings and use the custom CSS for the alternatives. You can add the custom CSS to the Custom CSS field of your templates parameters (Extensions -> Templates -> [YourTemplateStyle] -> Custom CSS).
