LOL, I'm here
This one isnt in my database, at least not an official release name, no there has never been this colour.
But it *might* be a working name, what I can say is that its NOT a WN for any pigment released in the last 3 years - I have all the WN for those, it could be an earlier one, pre 2007 if at all. I'd like to see a pic actually
