Hello Blake,

Thanks for writing to us.

To make the changes as requested, you will need to add some custom CSS code. To do this, please follow these steps:

From your WordPress dashboard, Navigate to Salient > General Settings > CSS/Script Related. In the custom code area, insert the provided CSS snippet:

#top .right-aligned-menu-items a.nectar-button.small.regular.regular-button:hover {
    background: #502db4 !important;
    color: #fff !important;
    font-size: 18px;
    font-weight: 400;
    line-height: 27px;
    margin-right: -15px !important;
}

Once the code is added, save and refresh the page to see if the change has been applied. In case it helps, please check this section from the documentation on CSS/Script Related.
