Hi alexmcdonaldwork,
First of all, take my apologies for the delay in answering.
1. Background color
Please add the following Custom CSS code to Theme Settings > Custom CSS > Global Custom CSS:
ul.wd-nav.wd-style-bg>li>a:before {
background-color: #fff;
}
2. Links colors
Go to Theme Settings > Typography > Advanced. In this area, you can assign elements like screenshot https://prnt.sc/MLRGF4WW_j1l
li:is(:hover,.current-menu-item,.wd-active,.active)>a
Please refer to our documentation https://xtemos.com/docs-topic/advanced-typography-settings/
