Ask your self, how many times have you heard it been called the others?
Maybe a few times, then think about how mnay times it has been reffered to as the Erdnase Colour Change

The colour change in RRTCM is not the Erdnase. So the question I posed was, what is it? In RRTCM it is simply referred to as the Colour Change.
As to the other names for the erdnase, I agree completely. Thats why I explicitly used the term common name. Having looked at all the contributions, I still think we have a bit of a problem.
1. Brad Christian presented a change which he called the Classic and the Houdini. He stated it wasn't the Erdnase. Correct me if I'm wrong magic_evmeister as I don't have Ninja 1.
2. Sankey presented the erdnase and also referred to it as the Houdini.
3. No one else has heard of the Classic Change, other than on Ninja 1 (or at least hasnt posted here).
Either Brad is wrong and they are all the Erdnase, in which case its academic and we can all forget about it.
Or theirs a colour change we don't know about.
