A few days ago, I've searched that too. We usually decide our facade colors from various RAL or NCS catalogs and it would be awesome that if we can import NCS colors like RAL goodies. I've even considered writing an e-mail to NCS because they have several templates for AutoCAD, PS, and Illustrator...
I found a user guide and some .pdf installation documents and 1-2 screenshots about that plugin, and some info as that plugin had a price tag on it; but not the plugin itself...
We just need some simple color importer like RAL, not re-discover NCS colors on the color triangle (or whatever they call their system).
