Color or Fonts in Messages app

I dont even know if this is possible but I figured I'd ask

Is there an app available that in some way can display messages from different email address in a different color, different font or some other way that lets you know which email address has received mail within the messages app?

ie: If you recieve an email from your work email it's red if its from your personal email its blue an sms green etc.

I asked a similar question like this a while back and I was told its not possible.

I wish someone would develop something.
