As far as I know, only the top two photos were posted by CNN, the rest were posted by others so I cannot assume authenticity.

That said, here is the second CNN photo:

The link is different from your photo.

Anyway, is it possible that the angle of the shot is causing the light to reflect differently off of the ink?

Also, this second CNN photo is signed by a different photographer. Perhaps their cameras are different and the first photographer had a better lens or higher resolution/density?

I rehosted the photo on imgur.com. That way, they can't delete it or change it.

If you download both versions and run a binary compare, you will find that they are the same length (58,961 bytes) and bit-for-bit identical.

That's possible.

It's also possible that the color shift is caused by over-compression. When you save a JPEG, you can set the compression level on a scale of 1 to 100. 80-90 will give excellent quality but a relatively large file. If you go for, say, 20, you will get a small file, but you run the risk of introducing noticeable compression artifacts.

The two photos definitely appear to have been taken by different cameras (or possibly the same camera with different settings). The first photo has ColorSync profile sRGB built-in. The second has no ColorSync profile.

The VSC-1 and VSC-4CX are instruments designed to detect the different optical properties of document materials. Unlike the VSC-1, the VSC-4CX is a portable instrument that can be taken outside the laboratory to examine documents in law offices, court rooms or other off-site locations.

VSC testing is non-destructive and does not alter the appearance or condition of a document. These instruments are particularly effective at detecting alterations to documents, restoring erased entries, revealing original writing that has been obliterated, obscured or overwritten and differentiating inks that cannot otherwise be distinguished by the naked eye.

.....Inks from different writing instruments often react differently when illuminated with ultraviolet and infrared light. These differences can easily be detected with the VSC-1 and VSC-2CX......

could be an infrared or other filter like flourescent light filter on the camera caused different colors to show up.
