Hi
in JA Builder there is Main Menu collapse in mobile view.
Add this code in builder custom css block to change its color

.jub-block .header .navbar-toggle .icon-bar, .jub-block.header .navbar-toggle .icon-bar {
    background-color: rgba(206, 53, 53, 0.4)!important;
}

If you are using any template, I need the site URL to check that.

Regards
