ELI5 why stars have the same colour when you look at them from earth, but in reality they have all kinds of colours?

They do not appear to have the same color when you look at them. If you are looking at them from the city or anywhere else there is light pollution you might have a hard time telling them apart, but on a clear night you can easily distinguish the colors of most bright stars. Try looking at a constellation with brighter stars like Orion and you will notice the difference. One of the stars in Orion is very red, while the others are blue.
