Would like all header text, title and icons to change to black when hovering on the adaptive header background.

I would like my header to function like rh.com when it comes to hovering on the header and having the text and background change color.

I have figured out most of the changes,  but I can not find how to change the color of all the text, site title and icons when I hover.

When you start out the text is white with adaptive header, when I hover on header the background changes white, but I can not figure out how to change the color, to black so it is visible, on all the nav text, site title and icons when I hover anywhere on the header. 

Can anyone help? Please :)

Whoa! Super cool ur the bomb! thank you! it works perfect.

The only thing that didn't change is that, I made it so when the screen is small instead of stacking the nav it turns into a hamburger. the hamburger did not change color and blends in do you know how to change that too?
