The faster a star moves towards the earth, the more its light is shifted to higher frequencies. In contrast, if a star is moving away from the earth, its light is shifted to lower frequencies on the color spectrum (towards the orange/red/infrared/microwave/radio end of the spectrum).

Explanation:
When a star emitting orange light moves away from the earth, its color will appear red. This is because of the phenomenon called Doppler shift.
Doppler Shift:
Doppler shift is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. In the case of light, the Doppler shift causes a shift in the color of the light.
Effect of Doppler Shift:
The Doppler shift causes a change in the color of the light emitted by a star. When a star moves away from the earth, the wavelength of the light emitted by the star appears to increase. This increase in wavelength causes a shift towards the red end of the spectrum, which is why the star appears red.
Conclusion:
Hence, when a star emitting orange light moves away from the earth, its color will appear red due to the Doppler shift.
