well stars appear white where as sun which is also a star appears to be yellow this has to do with the physiology of eye . The wavelengths of the light produced by stars and sun differs sun produces more wavelengths which are visible to our eye where as stars produce less wavelengths of light which can't be visible to the eye stars are also yellow,orange and blue but due to the structure of eye and the wavelength taking effects that stars are white where as sun is yellow

QGP: Actually, the sun produces white light.
QGP: Due to scattering of light by particles present in the atmosphere, the yellow light reaches our eye and so the sun appears yellow.
QGP: In case of far away stars, there isn't enough light to be scattered.
QGP: So, the stars appear white.
QGP: If you see carefully they have a bluish or a reddish hue, and not a white one.
QGP: This is because of the temperature of the stars.
QGP: Hotter Stars appear Blue whereas Colder Stars appear Red
QGP: This is due to Doppler Effect
RHarsha: kk
RHarsha: could u please say me about doppler effect

Answer:

Stars emit light over the full range of visible wavelengths. ... But fainter stars all appear white because they are mainly being seen by the rod cells in your eye, which are not very colour sensitive (and have no sensitivity to light at the extremes of red and blue).
