If there was, I didn't get the memo. Then again, no one ever sends me memos.
I wanted to say that I'm really enjoying this discussion - very civil and no name calling. Thanks for kicking it off!
Ok, with regard to your point, I can see what you're saying but that chart was just a counter-example to the premise that "no brown in town" is a hard and fast universal rule. This is the part I think is interesting:
It has never been as persistently fashionable as blues, greys or at times, black, but I have never come across a publication from the last two centuries that expressly stated a Rule forbidding it.
Out of interest, have you found anything to contradict this?
A question for you: do you find brown ties to be "not as versatile" with regard to colour matching or in a contextual sense?
