[Theme Horse Support Team]

Hi catherine,

Yes we always recommended to make a child theme before making any changes in theme to be safe from data loss while updating to our new version.
You may also change the CSS code from Dashboard-> Appearance -> Theme Options -> Design Options Tab -> Custom CSS paste the CSS code and Click on save all changes button
If you change only the Colour code #63C6AE to #D51C3B to match the company’s logo then there will not be any loss of content.

Thank you!
