How do I colorize some YAML code without affecting background colors?

[ssbarnea]

I currently use Syntax(text, 'yaml') in order to render some YAML files nicely on screen. Still I observed that this is changing the background color, something that is undesired, especially as some terminal users use darn-on-white schemes.

I tried giving a theme parameter like theme='ansi_dark' and this produced ok results, for normal terminals, until one of the users send me this:

Is there a way to configure rich in such way that it would render yaml without affecting background?

In that last screenshot I'm pretty sure you are using the default them of "monokai" which has a non-transparent background color. Use "ansi_light" or "ansi_dark" for a transparent background.

You can force the background color to be transparent with background_color="default" although that may produce unreadable text for some terminals.

Indeed his screenshot is made with an older version, i know that as it also has the border which I removed since.

Knowing that these two themes have transparent background is very useful, making them prime candidates for us.

My only question is: can't we assure that the default theme uses a transparent background on rich?

For the moment I will manually switch to ansi_dark but it will be awesome if default one would be transparent.

Monokai is the default theme because I think it looks the best. Obviously a personal choice. It existed prior to adding the ansi_* themes. I see no reason to change the default now, since its trivial to change.
