I finally got the bottom bar to be the color that I want instead of stupid gray. But whenever I’m moused over something in the system, it’s impossible to see what I’m really actually moused over. Is there a way to change that highlight color?

In the photo I’ve attached. It’s somewhat easy to see it, but in real life unless you’re sitting way off the side of the computer screen, you literally can’t see what is highlighted. It’s basically gray on gray. On a side note, I wanna meet the people who actually designed this interface give them a piece of my mind. But big question how do I change the highlight color of what I’m moused over.?
