Hi Sam, thank you for using our WordPress theme Crio to design your website!
Currently the color used when hovering over the links in menus is automatically calculated based on the standard link color and the background color selection for the menu. The existing controls for the hover design only allow for adding various hover effects, like underlines or background color changes, but we do have a feature request in with our development team to add a color changing option to the hover effects.
I updated that feature request with a link to this forum topic as well and I hope that we will be able to add some velocity to implementation of that feature.
In the meantime you can use some more Custom CSS to modify the color your menu items will use when hovered. Here is a snippet that should help you make the required changes:
.sm.main-menu .menu-item a:hover {
color: #123456;
}
You can swap out the color code used in that snippet to change the color applied on hover actions to any custom color that you need.
Please let us know if you have any other questions for us Sam, we are always happy to help!
