What is the best method to display mutual categories on profile page

I have a profile page where I'm showing the list of categories that user is part of. When a user visit other user's profile, he should be able to see mutual categories.

Each category has its own colour, and I am representing each category with icons.

One potential method to show mutual categories is use of respective category colour (as shown in the below image). Its differentiating mutual categories, but not in innovative way.

What is the recommended best user experience to display mutual categories?

Thanks
