Change slider button colour

Are you talking about the small circles under the slider or the left and right buttons? Can you send a link to the slider on your site?

My site is https://willothewisp.com.au/
And the Slider is in my Footer on all pages.
Sorry to have not been more specific- I’m referring to the small circles under the slider when I change the slider to slideshow style.

Try this…

.wprs_unslider-nav ol li {
border: 1px solid #000000;
}

.wprs_unslider-nav ol li.wprs_unslider-active {
background: #000000;
}

Thank very very much!

Yes that worked and is perfect.
Many thanks
