Hi! We think that most stars are actually smaller than the Sun, so that would tend to make them reddish (smaller middle aged stars are cooler and because of that are red - as stars get hotter they get yellow then white, and then blue for the hottest stars). The reason you don't see so many red stars when you look up is because small red stars tend to be dim too - the less common, bright ones (often white or even blue) are easier to see.
