XenForo Changing the color of the phone's header icons

[XFBOT]

I would like to change the colors of my icons in my header on the phone as they currently have the same color as the background.

Are you using a custom style?
For mine, I use the below code (I set custom icons for my items)

/* NavBar modifications */
.p-navEl a:before, .p-navEl :before,.offCanvasMenu--nav :before, .p-nav-list .p-navEl a.p-navEl-link:before {
    .m-faBase();
/*    display: inline-block;*/
    text-align: center;
/*    margin-right:5px;*/
    border-radius:30px;
    line-height:normal;
}
