Renders invisible colours when using dark theme

[lonix1]

Information

• OS: linux
• Version: ubuntu 20
• Terminal: gnome terminal
• zsh 5.8
• dotnet 6.0.400 with agnoster theme
• Spectre.Console 0.44.0

Describe the bug
Some items are rendered in colours which cannot be seen in the terminal.

To Reproduce

• create project

  dotnet new console -o Demo
  cd Demo
  dotnet add package Spectre.Console

• Add code from the getting started page
• $ dotnet run -- --help

Expected behavior
To be rendered so that I can see everything

Screenshots

Additional context
I thought it could be zsh, or zsh's "agnoster" theme. So I ran it in dash without any theming:

sh
dotnet run -- --help

That produced the same output as above, so it's not the shell.

I had an idea that maybe it's the terminal's theme. My gnome-terminal uses the extremely popular "Solarized Dark" theme. When I changed it to a light theme, I could see that text. So the conflict is definitely the terminal theme.

However, when I chose any other dark theme, I got the same problem - so the problem is dark themes in general.

Do the colours rendered by Spectre work nicely with dark themes?

Another example, using the code from the commands page:

Obviously it's just me.

If anyone else has this issue let me know maybe we can compare notes to repro the problem.

Solarized Dark theme was the problem, known issue.
