Can anyone tell which color stands for what?

I don't think they meant anything. But the colors are nice. For example, I have a red 9 since the day I was awarded it. It has never changed since then. Still, it is a great red star.

the color of the star is just a design it is the users rating or like how active you are or something your using rating is 7 its like gold member,silver member,platinumum member but on this site its kind of pointless doesen't do anything for you or actually i think it is the quality of your disscussions is what it is....
