SKY BLUE KYU HOTE HAI , OUR ATMOSPHERE IS MADE UP OF VERY TINY PARTICLES , IT CONTAIN 78% OF NITROGEN AND 21% OXYGEN , THE RAY OF SUN WHICH PASSES THROUGH THE ATMOSPHERE WHICH CONTAIN ALL SEVEN COLOUR BUT THE THREE OF THEM(VOILET , INDIGO AND BLUE) ARE SCATTERED ON ATMOSPHERE BECAUSE OF SHORT WAVELENGTH .THE VOILET AND INDIGO HAS SMALLEST WAVE LENGTH , BOTH SCATTER ON THE TOPEST LAYER OF ATMOSPHERE AND ONLY BLUE ARRIVE TO OUR EYES.

(VIBGYOR) by this you can refer that vilot, indigo and blue have less wavelength . And sun is nearer to our earth so because of this atmosphere can't refract much amount of light in day time. And same happens with sunset and surise time red has greater wavelength than blue and any other colour . That time sun is far from us because of that all colour refract only red color don't refract by this you can say that in sunrise and sunset time the sky is red
