For the menu items colors.
Please try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.
header.whb-header.whb-sticky-shadow.whb-scroll-slide.whb-sticky-clone.whb-hide-on-scroll .whb-color-light .navigation-style-default .item-level-0>a {
color: #000;
}
header.whb-header.whb-sticky-shadow.whb-scroll-slide.whb-sticky-clone.whb-hide-on-scroll .whb-color-light .navigation-style-default .item-level-0>a:hover {
color: #fff;
}
You can set the colors according to your needs.
Best Regards.
