Hi Dave,
As you mentioned, the low contrast in the status bar highlight is caused by the current theme. To resolve this, you can try switching to a different theme by going to Tools → Theme.
I tested several themes and found that some dark themes provide much better contrast for the status bar highlight. The most recommended option is the Visual Studio Theme Pack, because it supports many dark themes, and its status bar colors are designed with higher visibility.
Dark-mode themes from the Visual Studio Theme Pack that offer good contrast include:
- Cool Slate
- Icy Mint
- Juicy Plum
- Moonlight Glow
- Mystical Forest
- Abyss
- (and more)
From my testing, the Monokai theme appears to be the root cause of the issue. Its status bar highlight looks exactly like the one in your screenshot.
Although it is technically possible to customize a theme manually, I don’t recommend it. Custom theme modifications may cause unexpected UI issues in some situations. Switching to a different theme is the safest and most effective solution.
I hope this helps resolve your concern. If you have any other questions, feel free to let me know!
