I haven't found anything regarding color or such(or even proper names) for the different levels of chakra while playing my monk. However, I can say that the different levels are opened by gaining a certain(though unspecified) level of Aether within the body.
While the skills you learn are skills from the Fist of Rhalgar sect of monks, there very well could be other secs that have trained and learned to use the chakra gates for something less destructive.
