Minimize loss of block contrast when changing global style

[tenman]

Description
Global style changes occur independently of palette settings.
In some parts of Twenty Twenty Four / theme.json, --wp--preset--color--contrast-2 (text color) is specified,
This causes several blocks to lose contrast.

Step-by-step reproduction instructions
1 Set the background color of the global style to black and the text color to white.
2 Check the contrast of wp-block-post-date, wp-block-post-terms, wp-block-site-tagline, wp-block-quote in the front end.
3, Delete "color": {"background": "var(--wp--preset--color--base-2)"}, from each block in theme.json.
4 Check the contrast change on the front end.
Expected behavior
the text color of the body element is inherited.

Environment info

Additional context
Try creating a new post in Step 1.
The post title will be the same as the background color, making it difficult to type.
.is-dark-theme .wp-block-post-title{ color:#fff; }

In Step2, check the change in the background of header.html
Because the backgroundColor is specified, it will probably appear with a different background than the theme intended.

<!-- wp:group {"align":"wide","style":{"spacing":{"padding":{"top":"20px","bottom":"20px"}}},"backgroundColor":"base","color":"contrast","layout":{"type":"constrained"}} -->

If anyone changes the background colors, it is also their own responsibility to make texts readable.

As Carolina pointed out correctly, it's not a bug in the theme. The accessibility-readiness of the theme is referring to the colors provided by default. Since the blocks you pointed out have different colors from the main text color, you need to override them as well individually in the global styles.

Since it's not a bug of the theme, I'm closing this issue.
