Just to be clear, no. It’s not a 19th-century fake.
With that out of the way, I decided to take another look at a couple of things, and I noticed what some might consider to be
new evidence in the question of whether or not the manuscript is a modern fake.
One of the biggest ‘selling points’ for people who claim that it’s a fake is the difference in colour between the Leipzig leaves and the British Library leaves, according to the images at the
Codex Sinaiticus Project website. Despite at least one professional manuscript photographer
taking the time to explain why it is problematic to make arguments based on the colour of those images, the colour is still a point of emphasis from people who maintain that Codex Sinaiticus is a fake.
David Daniels, author of the book
Is the “World’s Oldest Bible” a Fake? (Ontario, CA: Chick Publications, 2017), recently posted a video (link and info in my longer note linked below) in which he again emphasised the colour of the leaves as part of his ‘evidence’.
So what about this new evidence I claim to have? Well, it’s not really new as much as it is a repackaging of old evidence into a way that more clearly shows why determining colour from images is a bad idea.

I’ve put a file online that goes into more detail, but I’ll give you the spoilers here.
When you compare the colour charts in the Leipzig images and the British Library images, it becomes clear that there is no way that these two sets of images were taken to the exact same standards. However, the clearest way to demonstrate this conclusion is to take a single colour from each of the colour charts, lay the two samples out in a mosaic like Daniels does, and then see how they look.
Obviously, the two sets of images were not taken to the level of precision that Daniels’ theory needs. If they were, we would see no difference in colour at all, because those two versions of yellow that you see in this image are the
exact same colour in real life.
For the full description (as well as a couple of other samples like this one using other colours from the colour charts, and an argument based on raking light images), see my note here:
