Defining AT: Color

Are there certain colors, brightness/dullness of colors, or patterns of colors that leads you to determine that a coin is definitely AT?

<< <i>Why a separate thread for this? >>
you know how threads get buried and mucked up....his first thread was on defining "intent".................this one is on defining the toning in questions coloring patterns that cause a coin to be deemed "at" or natural.
unfortunately many graders don't have that knowledge down to a science yet...and i fear that many many coins are lumped together in the "questionable color" category to avoid drawing a line in the dirt somewhere.

I am trying to keep the arguments focused on one factor only. Otherwise, we get arguments like, "That coin is obviously AT...any reasonable person can tell that."

2) That particular image, however, is a type of scan which shows the colors in what I believe to be an excessively "neon fluorescent" fashion
3) There are thousands of Morgans with vivid rainbow bag toning, known factually to have been NT under natural storage conditions over a very long period of time.
4) The type of colors shown on the BC and the ASE would require exceptionally unusual natural conditions to form ... but the ASE has not had the time, nor is known to have been stored in such conditions. Also, the pattern of toning is not suggestive of a natural condition. The presumption here would be AT ... unlike rainbow-toned Morgans, which are widely known to have come straight from Mint bags in that condition. Further, Morgans have been collected for decades, so there are already thousands of coins out there with naturally acquired album or envelope toning ... the same cannot be said for the ASE.
Conclusion: BC Morgan, blatantly NT ..... ASE, blatantly AT
