Hi!

This PR would be a breaking change for users who is not using the text color option, or that uses an older WordPress version where the text color option is not enabled.

On existing sites, the text color that is already in use would be removed, and that would be an unexpected change for users.
Also, please consider that the quote text and citation text has different colors in this theme, and that the design should be respected.

In WordPress 6.0.2, pull quote blocks that has a text color added with the color option receives a CSS class called has-text-color. Have you tried using that class to limit the CSS change to when the color option is in use?

This only applies to the blockquote when the user has chosen any color which means blockquote parent .has-text-color class in it. Otherwise, It always has the default color.
