Menu Color change when scroll and open menu, but

I have a question, i make my Nav change from White > Black when i scroll down home-project-section. But then i have a problem is when i open Full-screen-menu (Black BG), Nav is black. Its not what i want.

So I want my Nav to change to white no matter what color it is currently, and after closing the menu, Nav reverts to its current color before opening the menu.

What should i do? PLease help me!
Thank you guys!!
