I know what you mean. The Visions of Treachery poster that Black Library sell depicts them in a strong magenta shade. However, the above are correct.So the EC are my favorite pre-Heresy Legion but there's one thing I wanted to clarify. Lots of people paint up their pre-Heresy EC in purple, while there are illustrations depicting them both in a pink-ish magenta and purple. Just which one is the "correct" colour?
