Buttons color

Hi! How to change color blue to red in the module (see the screen), please advice.

You can add this code in custom section

.jub-block.testimonials-5 .testimonials .swiper-pagination-bullet-active {
background-color:#your red color;
}

Thanks! I added the code to - templates/ja_builder/css/custom.css
Is it correct? But it's not working.

You need to add it in the settings section -> Custom.css ->

It works now as you can see.

Oh, great, thanks a lot!)
