Hello,
1) I checked your home page and see your changes https://prnt.sc/26f7ayu
Also, I have tried to change the font color and it also works https://prnt.sc/26f7c4b
So, make sure that you clear the cache after your changes.
2) Provide us with FTP access to your site. We’ll check the issue in more detail. Seems that it displays product description there by mistake. We need to check why.
Regards
