Can you change the color of a username or add a logo next to it?

Hi Everyone, 

We have a Community that is used heavily by a few groups: customers with questions about our products, expert users that provide support, and company employees that provide support. It can be hard to tell which of the latter two groups have answered a question since you cannot see their roles and badges unless you hover over their username. In order to make these groups easier to distinguish, we were wondering if it is possible to assign a text color to a given role or add a logo that appears after their name. Is this something that can be edited on the site as is, or does it need a customization? 

Thank you in advance.
