Slider color

Hello,

I can’t see anywhere on backend / css how i can change the slider background color.

Currently it’s #CCC!important checking with Inspect Element but isn’t on any CSS, it appears on (index):462

The code:

.ccb-wrapper-2986 .e-control-wrapper.e-slider-container.e-horizontal .e-slider-track {
background: #ccc !important;
}

Thank you!
