NavBar Menu Icon Colors in Dark Mode

[BryanJDaniel]

Trying to build a Dark Mode Focused application
And have enough color to reduce as much white-light brightness as possible.
(It just hurts my eyes too much)

Unable to get the icon colored to work when dark.css is applied It's staying as White,
Other color aspects seem to be working including Active Color, Menu Title Color
But just not the icon colors.

What would you recommend to fix/enable this?
