I would say that the images from my r1 consistently show a green cast. Not a problem per se, when it’s easy to ‘fix it in post’ and not a problem for rabbit vision. (I do note that my album of magic camera images lean towards green overall.) But it is perhaps something that could be corrected for the originals on the server end with a standard magenta shift, or even an auto white balance feature in a tool like ImageMagick on the server.
