I don't think sun fading would turn that from green to blue.

Green is easily turned into blue, with nothing but light.
If too much light (or other factors beyond quantity), colors beyond yellow-to-white and green-to-blue get dulled. Attached is an example, the bottom of the card on top was covered with a book, and the rest of the card hit with a certain kind of light. We can see the image is dulled out and washed out, because I hit it with a lot of light for a longer time, to illustrate the effect.
One can easily create a version that does not dull the other colors but using more moderate light and/or different light sources. These can happen for non-nefarious reasons too, for example a card left on display and exposed to light of the right brightness range for long enough, but some scammers have been making cards like this for awhile to sell as 'errors'. These undulled or less dull cards are often incorrectly believed to be 'legitimate'.
Yellow to white, green to blue, and for tobacco cards red to orange are the easiest color changes to have happen through honest exposure or through nefarious means intending to defraud. All can be made pretty quickly at home. The most problematic of these are probably the 1969 Topps white letter Mantle's. There is a true printing variation, with his last name in yellow or in white, with white being rare. However, you can pretty easily just remove the yellow in that area and make one at home.
Glues can create much weirder combinations and color problems, which are also often passed off as legitimate printing errors, but really are not. A majority of color-based printing errors are not errors and did not leave the factory that way.
