New Color Variety For Scott 620?

I recently pulled this out of an APS sales circuit, not because it has a graded certificate, but because of the deep lake-like color. I've checked, and while there are a number of stamps of this period with a lake variety added, this is not one of them. The shade is very different from the usual carmine, which I've included for side by side comparison. I'd be interested to hear what others think of this.





This is the "lake" shade stamp.




Here's a 219D for comparison.




This is the normal carmine shade.

Is it possible to scan both stamps at time? It would be great if you could include a #219d in the scan too.

The Scott US Specialized catalogue does mention a "deep carmine" for this stamp. Perhaps this is what you have. I agree with Don, it would help to see the stamps side-by-side with a known lake variety in a single scan.
Added: Went to the Philatelic Foundation web site & looked at their certs for 620. The range of colors pretty much match your two stamps ... of course, like your stamps, each stamp has been scanned separately which makes color comparisons a bit difficult. They do have one "deep carmine" cert ... it doesn't look like your "lake". I would almost call it an "intense" or "bright" carmine. Several of the "normal" carmine 620s are similar to your stamps.

your "normal" carmine looks a bit light to me

I'm willing to believe in this, but I agree that all 3 stamps should be concurrently scanned side-by-side on the scanner. It's the only way to make a fair comparison. I agree the "carmine" stamp looks bright or light.

Possibly lightly oxidized ink? Look for a bubbly surface under high magnification. I know it happens on some early British stamps in that color range, not sure about US.

It doesn't look dark enough to be lake. Even side beside it isn't dark enough. Its more of a deep carmine on this end.

Here's the side by side. Since some had commented the single was bright carmine, I added the block of nine for comparison.

definitely a difference, but I'll have to let others say if lake or deep carmine

A deep, rich, lively carmine but I'm sure others see better than I and will chime in.

While it appears closer to the lake color of your 219D than to the carmine of the other 620s, I still think I detect a difference between the colors of the 219D and the 620 in question. It seems to me that there isn't quite enough blue in the 620 color. The CV for the carmine & deep carmine are the same, so the latter should not be rare, meaning your 620 could easily be deep carmine. But then my color sense has never been all that good. Judging from the certs I perused, if you were to have it expertized, I think it could come back as either carmine or deep carmine, with carmine actually being the more likely choice ... but probably not lake.

Look carefully at the fine lines in the design with a 10 or 15 power loupe. The image leaves the impression that the stamp is a bit Sulphurized affecting the solidly inked areas more than the fine lines. One test is to compare the color of the fine lines with the solid areas.
