Let me start by saying I know very little CSS code. That’s the main reason I purchased GP Premium, so I could customize my site without it. Having said that, When I go to Colors I see a Navigation Color Presets option which changes the background color of the menu, but I don’t see a hover color option. Can I change the Navigation Hover Color and, if so, how?
Here’s a demo video of what options you should see under Customize > Colors > Primary Navigation(or Secondary) and how you can change navigation colors. https://share.getcloudapp.com/d5uEQXz1
You should be able to see “Background Hover” and “Text Hover” on both Parent items and Sub-menu Items.
