Never heard of that. However the only coding I have heard was that a dark blue is medium aggressive, red was aggressive and yellow/grey/light blue/white are synthetic polymers which are a lot easier to use than the original two as far as plyability and which they re-labeled to fine and ultra fine. I don't even think you can buy the aggressive one/red one anymore. Now bring in some imported clay then it gets real confusing.
