Highlight or Color Code emails from known Contacts

I like the concept of making it more clear which emails are from my contacts and which aren’t but I don’t like to move these emails out of my Inbox as explained in: Move emails from unknown Contacts out of your Inbox folder.

Can I highlight emails from my known Contacts in my Inbox folder instead?

Color Code Contacts buttonYes, this approach is also possible when you use Color Categories. You can choose whether you want to assign a Color Category to your known or unknown contacts.
