I don’t like the fact that you have to use the website theme to customize some things like font and color.
How would you like to change the color and font of your site?
This option is usually provided by the theme as you mentioned, the Twenty Twenty Two theme comes with a new feature called Full Site Editing. This option allows you to edit the style of the site in a way you like using Global Settings.
If you go to Appearance > Editor you can change your site’s font style and color as shown in this short video.
Alternatively, you can also change the style to your preference on each block as shown in this short video.
