I've decided that my next tartan kilt will be the Clergy tartan. I've done a lot of research and found that the Clark tartan is the same. However, I was reading the thread on Militery Tartans and noticed that MacWage mentioned that the more modern mills try to differentiate them by the colors used. Now I'm wondering, which mills do this and in what way? I've not seen any examples of this so far and I'll admit that I may have missed them.
