change hover color on current menu

Here is the site: https://vertigoforextrading.com. The current menu item needs to stay white when you look at it normally, but on hover there is a white hover background so it needs to change to black font. If I change it to black it is also black when you look at it normally. There isn't a spot in the customizer as far as I can see to change the hover color for the current menu font. I know there is css for this but I can't get the right selector. Also, why isn't there an option for current hover in the customizer? Thanks!
