We know, As per Doppler effect, if an object travels with speed close to that of light, if appears red if it goes away from observer and it appears blue if it comes towards the observer.
My question is what will happen if
The object itself is of red color and going away from observer nearly with speed of light
The object is of blue color and coming towards the observer nearly with speed of light.
This is my first day on this platform. I am sorry if i have typed anything wrong.
