Keep in mind if your monitor isn't properly calibrated (or just has poor color accuracy in general) that you will not be seeing the *actual* colors represented by the images that intelli78 is posting. I think a lot of us will just have to trust him on this one 
I am a little confused as to how we can even come to a consensus when there is variability between what people are seeing on their monitors. What Intelli is seeing on his calibrated retina display is definitely not the same as what others have.
I trust Intelli's intuition as to what looks best and what represents the original TA set best.
As for windows keys, eh. I thought the layout of the set was set in stone.
Yes, to a large degree me sharing this info may be doing more harm than good, as only folks with factory calibrated retina MBP monitors are likely to see what I'm seeing. (And maybe not even all those, as calibrations and manufacturers can vary even on the same MacBook models.)
If we really wanted to be looking at the same photos, we'd all have to order
Spyders or similar products.
However, one good thing about Pantone colors is that they have real life reference points, so anybody who can get access to Pantone color books can see what I'm seeing in person.
I think we should be focused on what looks best, not on what's the closest to 100% accurate. Remember, every set we've seen looks different due to differences in how they've aged. As such, accuracy is not a perfect ideal you can strive toward. Aesthetics, on the other hand, is.
Edit: auto-correct hates me.
I understand what you're saying and I basically agree. That said, what I am trying to achieve is not necessarily "accuracy" in the abstract as much as copying Josh's photos from the OP (the first 3 photos in particular). No, we won't be able to duplicate it 100% either, but I'd like to get the teal a little closer, as the 5473 is really just a dark green with no blue.
It sounds like everyone is pretty much OK with the gray and blue, and I'm content to call those good enough.
More teals:
3155 and 7470 look like the most interesting alternatives here.

Is it possible for you to get all of these color chips so you can compare them side by side, then pick the one that looks the best? I think the current grey and blue are good fits.
Yes, most of them. I have to order individual Pantone catalog pages (each page only has 7 colors; the whole catalog is thousands of dollars). Of the different teals I just posted, I just ordered all the associated pages that Hyatt's has in stock. This will give me quite a few new options to consider, and hopefully one of them will be good enough.
Should receive the additional pages in 2-3 days, and will post an update then.
