Jul 19, 2015 at 3:10 comment added userLTK I'm going to throw this out there, but to the observer, it's never a green Photon, it's always red. To the object that generates the photon, it's always green, The energy changes if the frame of reference changes, but that's true for Newtonian physics as well, like throwing baseballs off a train.
