Consider a situation in which a charged object which is colorless in a stationary (w.r.t observer) frame is accelerating in a circular path such that it radiates EM waves of specific frequency (corresponding to say green color). Now consider an observer orbiting with the same angular velocity. Now with respect to the orbiting observer the charge is stationary but according to the frame of reference of the body the observer and charge orbiting the body should appear green(because its accelerating). But the observer who does not see any radiated EM waves should view the object as colorless.
So what is the color of the object ?.
Does color also depend on observer's relative motion w.r.t source.
If it does is their someway I could do this practically and prove that such is possible?
