Explanation:
For a star moving away from an observer, the wavelength of the light emitted by the star becomes (shifts) longer and the light is seen to shift towards the longer red end of the spectrum of light
When the the star moves towards the observer, the light is seen to have shorter wavelength such that the light is observed to move towards the blue (shorter wavelength) end of the spectrum of light
Therefore, the astronomer, will rather observe a redshift for the receding star
