Those are a great example.
I can't even rag on Ilias eyes anymore, 2 official artists for her variants went blue over teal.
One final example unrelated to anything is how Tifa is pretty much always black hair, despite the fact that her hair was brown on her models in the original, arguably a little lighter than Aeris. But she became so associated with the black in fanart that it bounced back to becoming official with all the 3D stuff.
