Naming no names and discussing no specific forbidden third party things, but from researching the thingy the OP implied existed, the client absolutely receives this information as part of incoming damage network info. In fact, it also natively has the ability to change the color of damage text but they haven't made use of it. While edge cases may abound, there's a third party *cough* nonexistent *cough* tool that does this on a basic level with a relatively simple script.
