Changing Selected File color

I’ve been playing with the color settings in the Windows Beta but there are two colors I can’t seem to change. They are different between themes, though, leading me to believe there is a way and I’m just not seeing it.

The two colors that pop up when you select a file (the light grey, and bright blue below).

Probably need to post this in the beta test forum so they can address it: https://www.literatureandlatte.com/forum/viewforum.php?f=57.
