Perfect tracking window background color?

[Goregasmic]

I put the background to opaque and when I try to pick a color it seems no matter what I pick there's a consider color that blends too much into the background and becomes unreadable. Like if you put it to black, dark blue becomes hard to read. Transparent depends a lot on the zone color scheme. If you put a variation of white the yellow cons become hard to read. You get the gist.

Anyone figured something out? Tired of squinting.
