Aug 16, 2019 at 16:49 comment added Nico Brenner Thank you for your answer. You are right, a real Doppler effect measurement doesn't make sense in this contest. What I meant to ask is: what happens if we interpret colors in an image as if they were caused by a Doppler shift from an arbitrary base frequency we pick from the image? So, just conceptually, think of colors in an image as being the consequence of a relative speed difference between the different light frequencies that make up an image. I know this doesn't actually happen (ie. all light travels at c), but what if we interpret it that way?
