If you are looking to change the slider’s dots please use the below code:
.slick-dots li button::before {
border: 2px solid white !important;
}
To change the arrows’ color use this code:
.modula-slider .modula-items .slick-next, .modula-slider .modula-items .slick-prev, .modula-slider .modula-slider-nav .slick-next, .modula-slider .modula-slider-nav .slick-prev {
color: white !important;
}
You can replace the value ‘white’ with the color you want.
