vantage theme drop down menu hover colour

Hello,

When I hover over one of the child items on my menu, the text colour changes to that hover colour (great), but the text colour of the parent is the hover colour, too. Is there any way to have it turn back to the regular text colour once the mouse isn’t hovering over it anymore?

This example is perfect: when you hover over “support” it is blue, but when you go down to documentation, the word “support” goes white again. (In my case, both support and documentation would be blue…)

Thanks in advance if someone has an idea of how to change this!
