Change color of X 'Close Menu' Icon

I'm designing a mobile version of an Experience Builder app and have an expandable menu at the top of the screen. Is there a way to change the color of the X icon that closes the menu? I have a dark background and the black X is very hard to see:

The panel color is controlled by the 'Light' color from theme configurations

The close button color is inherited by the 'Dark' theme color array

The 'Dark' theme seems to control the panel color on mine. Changing the 'Light' theme color does nothing.

That sounds odd. Maybe I ask - what environment and version are you using?
