I'm sure most of you already know, but GW changed their colours. New manufacturer, new formulas, new names. I've included their conversion chart for you guys to reference, but I don't know how accurate it is. Check out how the same colour is recommended for both Dark Angels Green and Orkhide Shade. I'm skeptical.
I'll be getting some of these in the near future in order to test them out myself. The next few Step-by-Steps will probably still use the old names until I figure out what matches what.
