Joe---
First of all, I hope you don't mind my using your images of the Stones in my posts. I assumed it would be OK, and I don't think I always credited you in every post, over the months, so I want to fully credit you now for taking the pictures at the museum, and I feel I should make it clear that they are yours, and I hope it's permissible to use them my posts as much I have.
Also thanks for posting the "bumper pictures." That Heart looks much darker than the Trail Stones.
For a description of the color of the Heart Stone in your museum photos, if asked, I would say "reddish" with a yellow tinge. I've always thought of them as more red than even brown, and certainly not "tan," as the Trail Maps appear to me.
Color blindness has different types, also, involving different colors. While it could account for one person's description of the color of a stone, the McGee article was written by both of them, so they would both have had to have, not only color blindness, but the same type of it. While that's not impossible, what are the odds?
Also they would both have to be unaware of their eye conditions, because if they knew about it, they would certainly check with someone else on the color of the Heart Stone they observed, before putting their description in a publication. While I have heard of some people not realizing they are color blind, at least early in life, I think it's a stretch that neither of them would be aware of it. I'm sure that if one of them knew about being color blind, it would come up in conversation sooner or later, and the other would become aware of their colors being off, also.
So, I think, altogether, the odds are heavily against it being a case of color blindness.

I do realize that geologists refer to some stone colors by their known references, rather than to the color directly observed on a particular specimen of that stone type. That shows in some of the reference photos I included.
But the McGees apparently weren't geologists, because all their references to color say "yellowish rock."
But in one of their three references to "yellowish...," in their very next sentence they add that it was "Reportedly cut from a slab of red chalcedony." This could be the very same type of geologists identification to which you referred. In other words, it seems to have been a yellow piece of red chalcedony. If there
is such a thing.
Curiously, if the Heart which they saw was, indeed, yellowish in color, it would need to go through the oxidation effects that you mentioned, sometime between then and when Joe took the photos of it that have been posted above. That's quite a bit of change for that time period. And if the surface color did go through a change, then why didn't the surface
inside the markings change as well? The carved portions of the surface would have been exposed to air for the same amount of time.
I know that turquoise in jewelry gets darker from being handled, from skin oils---but the museum photographed Heart is reddish all over, and that would mean a
lot of handling, from which I would expect most of the color change to be around the edges, and hardly any in the center area.
For all of those reasons, it doesn't seem that it's the same Heart Stone.

The problem I see with the "memory" idea, is that they specifically note about memory in the caption under the Priest Stone, even though it's a small part of their drawing, as they also mention a few other sources which were diagrammatic (which they could directly copy from). If they bothered to mention memory when it was only a small part of the composition of the Priest Stone, then surely the would so state it for the Heart if it was
entirely from memory.
The fact that they tell the color of the Heart Stone, three separate times, indicates that they were looking at it, and drew it accurately. And their drawing is not just slightly different than the museum Heart, but rather it's a lot different!
This again is saying that the Heart they depicted is a different Stone than what is seen in the museum
and all the replicas.

Another glaring contradiction in the McGee's article, is that they say it was made from a yellowish piece of "reportedly" red chalcedony; while the Director of the
Mineralogy Museum made
special note that it appeared to be
quartzite, and definitely "not chalcedony."
The only thing I can get from that is maybe the McGee's had received
information that the Heart was red chalcedony, but what they observed was yellowish rock, so they emphasized this by specifically using the term "reportedly" when telling about it. It seems like they wondered, too, why the Heart they saw was "yellowish." Maybe they suspected some funny business, because of the seemingly different colors, but didn't want to make waves with people who they relied upon for information, so only
hinted that something seemed odd about it. That does make sense, actually.
There is also the additional discrepancy that the Mineralogy Museum Director states the color of
all of the "other three" Stones to be
gray.
