Hi, thanks for this feedback. In the release 4+ I've implemented more theme combination, where you can find also some one with a "high-contrast".

Anyway, I'm sorry about this issue, can you open an issue on GitHub, so we can work together to create a theme with a good color combination?

Thanks

**Update: please, try the 4.4 version which should contain many improvements (you're using the 3.11.2.2)
