Opinion, #220 Color Error?

Hello everyone, what do you think—could this be a color mistake? Was the color taken from #229 (90C orange variant)? Thanks, and greetings to all.

Most likely sun faded

I agree. Red inks on early US stamps fades very quickly in the sunlight.

I understand that over time it can fade and become light red or light lake,but what I don't understand is how it can change from carmine and lake to orange.

It doesn't look orange to me. Can you scan them side by side with a true 229? To me, your specimen looks more like a light vermillion, not the bright orange of a 229.

#229 also has several orange variants, including red-orange. I'll try to compare them side by side a bit later and post the photos here.

It is extremely hard to judge colors on used, older stamps that have probably been through quite a life. I don't see anything special here, but others might.

I don't have the 90c stamp, and I wasn't able to photograph it side by side. I used available photos for comparison.

Comparing colours using images found online or on different devices is tricky.
Even the picture you posted will not show the same colour to all of us.

And that is even before taking into consideration that the two stamps compared have been printed at different moments and, likely, from individually mixed batches of ink. They also have been out-and-about where they were not cared for as a philatelist would and, probably, in different places.

Of course, it works both ways. A match may not exist. An apparent absence of a match may just be apparent.

Thank you for the comments and advice. I don't have the original 229 stamp, and even if I did, I would probably need quite a few of them to make a quality comparison. The 229 was printed in orange, yellow-orange, and red-orange, and each of them has its own variations due to the conditions under which they were preserved.

I think Zebra Man was right, and it is a light vermilion color. The question remains whether #220 was printed in that color by mistake, or what?

No.

You are discounting the fact that the three listed colors are not carved in stone as there is variance in the original printing process even before being stored for a century of so. The colors Scott listings are really "main general group" colors of an issue with a wide range of minor color variation.
