It you notice on the one with the red, on the left side near the face you can see some of the orange. I think in the sunlight theory that the red layer is faded away to reveal the color(s) underneath.

Take a look at the picture I have attached. The halftone dots are all at different angles for each color (Black, Cyan, Magenta and Yellow). Look at both of the McGinnity's with a powerful loupe and see if the magenta dots are running at the same angle on both cards. It is very possible that a yellow negative was shot on a magenta plate for the one on the left. Then it was caught by someone and a new plate was made with the correct negative on the correct plate.

Also, it is possible that the magenta and yellow plates were mislabeled before they went to press or the pressman put the yellow plate on the magenta cylinder and the magenta plate on the yellow cylinder and then caught the mistake and swapped the plates.
