When a star or galaxy is moving away from us, we observe the Doppler effect by seeing the lines in its spectrumAred-shifted (shifted toward the red end of the light spectrum)Bblue-shifted (shifted toward the blue or violet end of the light spectrum)Cyellow-shifted (shifted so all the colors become a little bit yellower)Dbecome darker and darker (like a blackbody)Eyou can't fool me, the Doppler effect only applies to motions on Earth, not to the motions of the stars and galaxies
