If you look at the stars fo far distance from you, may find an extra-ordinary consequence that it is getting more red. This consequence is just similar with the cars passing through you at night and going distance from you.
Light of the car will tend to turn into more red with the increasing of distance between you and car. This phenomena is called redshift.
In terms of galaxies and stars this is called Galactic redshift. Each and everything in universe getting distance from each other. The the stars in our galaxies are continuously getting distance from us. For that reason stars are looking as progressing brighter red color.
