[BUG] Plain code blocks do not render correctly on a light background

[genovese]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Describe the bug

Markdown code blocks are rendering illegibly and ignoring any styling in the theme given to the console. The code has a black background and the text, rather than being a cyan, is just unstyled text. So on bright backgrounds this is effectively black on black (one can barely make out letter shapes); on dark backgrounds you see the text but not as styled. Inline markdown code displays fine and changes styles as expected. But neither the default code_block theme or any new theme attached to the console seems to change the output from none on black.

I've attached an image showing this. You can see the inline markdown code and the code block.

Platform

Click to expand

What platform (Win/Linux/Mac) are you running on? What terminal software are you using?

Running on Mac OS 12.6.1. The same thing happens on standard Terminal and on ITerm2.
Note that the styles show up in python -m rich.default_styles, so it is not that the styles
are unable to display.

I may ask you to copy and paste the output of the following commands. It may save some time if you do it now.

If you're using Rich in a terminal:

python -m rich.diagnose
pip freeze | grep rich

The output of the second one is 'rich==13.5.2'

The output of the first is

This is as minimal as I can get it. Should have mentioned that this happens directly. It produces output just like what I showed.

>>> from rich.markdown import Markdown
>>> from rich.console import Console
>>> console = Console()
>>> console.print(Markdown("""

... """))

Is this sufficient for your needs?

[willmcgugan]

It's not a minimally reproducable example if I cant cut and paste it. Regardless though, I can reproduce this on a light background.

I hope we solved your problem.
