@sneak Looks like it's "just" a misadjusted white balance. While it's always to have a correct while balance set on the camera, it's a minor issue IF you shot this picture in RAW (easy/fast to correct by editing the RAW file).
But if you shot it in JPG-only mode, its harder/slower, or even impossible to correct the white balance afterward, depending on how the WB balance setting was far from the correct value.
@devnull the white balance was set correctly, the color is pretty close to accurate.
