In the project settings under the Styles tab, you can centrally define colors and typographies for your project and reuse them in the editor at any time. This feature is now also available at the publication level in the publication settings. You can now define and customize colors and typographies specifically for individual publications without changing the styles of the entire project.
By default, each publication in the project adopts the styles from the project settings. Any changes you make in the publication settings apply exclusively to that publication and thus override the project styles.
You can reset the settings to the project styles at any time using the reset icon in the respective fields.
Here you can find the What's New article about project styles.
