Help with changing specific tab colors (Explorer)

I switch between dark and light mode on my device daily, so that can be a complication factor in dealing with this. Currently, my tab title bar colours when using Explorer in light mode can be difficult to read to outright illegible in two occasions: 

1. Single tab: tab title text is white 

2. 2+ tabs: unselected tab is light grey when the window is focused.

This is in contrast to when the whole window is unfocused, where the unselected tab is legible.
