Hi Scott,
anytime custom CSS should work, this is current color styles:
.offcanvas-menu .offcanvas-inner ul.menu > li a:hover,
.offcanvas-menu .offcanvas-inner ul.menu > li a:focus,
.offcanvas-menu .offcanvas-inner ul.menu > li span:hover,
.offcanvas-menu .offcanvas-inner ul.menu > li span:focus {color: #ffffff; }
.offcanvas-menu .offcanvas-inner ul.menu li.active a {color: #000000 !important;}
.offcanvas-menu .offcanvas-inner ul.menu > li a,
.offcanvas-menu .offcanvas-inner ul.menu > li span {
color: #cb9b42;}
if you want to change ... override with a different color
