1868 & 1877 1 Fr Telegraph Stamp Color Questions

I'm two stamps short of completing my Swiss telegraph stamp section of my album. I'm a bit perplexed at times about the 1 FR Green versions though. Obviously the 1881 version has threads in the paper and the green is very distinct.
There is a wide range of shades of colors with these stamps, so it's already a bit confusing, and then peoples photos look different depending on cameras and lighting.
I'm seeing what I think are carmine centered stamps showing up in auctions as the 1877 red version, but the color of green looks properly yellow/green for the 1877 release. Then I see some that look almost exactly the same listed as the 1868 release with an attest. I have to wonder about the efficacy of attests in general, since I have an attest for a 10c telegraph listed as being from 1868 (those weren't issued until 1877).
Just curious if anyone has additional tips aside from looking at the yellow/green hue of the stamp mixed with the shade of red or carmine and if it has threads or not. Not sure if these is anything more and it's kind of a crap shoot. Maybe my ability to sense the difference between carmine and a dark red is not up to snuff. Curious what other collectors would label the images of the stamps I'm attaching.

Not a specialist.
Offering my few, for perhaps your study.

Thank you. I've spent some time on that site you reference. Definitely a good resource and one of the few resources about Swiss telegraphs in English. It's interesting that the catalog referenced there has multiple shade definitions for a series while Zumstein and SBK do not. I just found a good German site that really digs into the history, such as the metallic copper 3Fr was swapped for the mustard brown in part because the metallic surface was hard to postmark. Also, apparently the 1877 red was very susceptible to fading which may explain some of the wild color swings for that. Still not sure what to think about the wild variances in green being attributed to the 1868 1Fr, and sometimes I feel like the seller is misattributing a dark red as carmine, which is why I'm here. Maybe someone can set me straight.

As an example of variability, these two are on an auction site from the same seller. Both are labelled as 1968 Zum #3. The first I wouldn't question for a second. The second on the other hand.....

Tip.
One should always reference their source.
My reference helped you.

Withholding resources denies all students of Swiss philately
the continuing journey, and spoils our knowledge base.

Collectors come here for mostly instant solutions to all sorts of queries
because we have a shared knowledge ethos.

...and denies the original author's hard work.

My apologies! The sentence was supposed to include the words "which I will share when I find it again" which just what I was coming back to do now. I agree 100%. Was just rushing before and thought I had indicated that I intended to share. Oops.
Here you go.

Btw, here's my Lindner sheet and my 1868 and 1881 1 Fr.

Thanks for the link
A worthy site indeed.

Nice work on your page too.
Always was fond of these stamps, when arrived in 'swaps"

So you have a mount inside a mount, not seen that before.

Not sure what you mean by a mount inside a mount?
Throwing up some other closeups from my collection. The 50c carmine is almost purple to my eye.

It looks like you have each stamp in a showguard or top opener mount,
then placed in the Lindner sleeve pocket
Kinda like double protection.

I don't know anything about these but I find the first 3f on the last page interesting.

Rod222 - the black frame is just the box on the Lindner page. I did do what you said with some standing Helvetias that weren't included in the pages, just out of convenience until I mount the mount under the clear sheet. Eventually I hope to put in mounts for all the stamps in that book for the postmarked copy and the clear Lindner sheet will hold the mint versions which will lay over the postmarked ones. I'm guessing that it was my extra 3 FR stamp on the fourth line right hand side that I just have in there with no frame that was the source of the confusion.

Just fella - The original gold leaf one that they discontinued due to issues around trying to postmark them? If so, I find them interesting too. Here's a close up of one of mine.

Aha! I see now.
Not seen that routine before. Unusual.

Ruckuscollector,
Yes that is the one, thank you for the explanation,
not being familiar with these It really stood out from the others.

One thing I find curious about them switching from gilded to golden brown is that they kept running the gilded 1 Fr sitting Helvetias through all three changes they made in that same period. Not sure what made telegraphs more challenging than regular stamps.

For anyone curious about telegraph stamps, I'll note that most (all of the 1800s and most later soldier stamps) Swiss stamps tied in some way to the telegraph have the symbol of a star and usually symmetrical lightening bolts coming out of the star on them. You can see it in the corners of the 1800 series and those include similar wings around the star like the portomarken of that era. Later going into WWII, the symbol is much more clear on the soldier stamps of that era. I really appreciate the little flourishes that artists would put into stamps.
