Hey Curtix, this is a response to the question you posted on the thread I created.
So I have no idea how to remove it, but I found how to change the color.
The person that made this didn’t assign it a color, he assigned the background an image named slider.jpg that is a square of the grey color you see behind the images.
So, in the promotion slider folder under plugins, open the slider.css file.
Change this line,
.promo_slider .panel { background:url(‘images/slide.png’); -leave the rest (or don’t)
to this:
.promo_slider .panel { background-color: #whatevercolor; (hexadecimal)
that’ll change the color for you.
