Formatting page and text

Hi guys,

I am new to WordPress and English is my second language, so I apologize in advance.

How do I change this https://vetiveriastatera.com/about-vetiveria-statera/?preview=true&preview_id=11&preview_nonce=a233760173

I would like the text still justified but in the middle of the page, not all spread out, plus I would like to change the color of that title “Vetiveria Unveiled” which is right now light grey.

Thank you
