Hey there mizzymac,
How are you doing today?
Please try adding the following CSS code in the style.css file of your child theme or if your theme doesn’t have custom CSS tab add it in your site using the following plugin:
http://wordpress.org/plugins/simple-custom-css
@media screen and (min-width: 768px) {
#site-navigation.main-navigation ul ul a:hover {
color: #B3A9DB;
}
}
This should change your dropdown link hover color.
Hope this helps and have a nice weekend!
cheers,
Bojan
